The Dogcati

[husaberg]

It got its nom de plume Dogcati from Grumph. He suggested Dogcati instead of rescue Mutt. Yes I noticed t is far from pretty, but the price was right.
So follow the journey of an ugly duckling which is hounded into submission.


I just bought a cafe bike with a brown seat
cut mufflers and subframe and striped and clear coated tank stripped fairing street fighter weird led light
almost like those french monstrosities they used to have occasionally in FB and PB in the 90's
I call it rescue mutt.
The budget is $5k (includes purchase), and the target end date is Feb 21st, 2025.

Anyone who knows me knows I often don't finish shit...... But who knows this might be the exception, it's certainly is exceptionally ugly.<_<


Gonna need a picture. Hopefully its a GN250 cafe. Or an SR400


Dogcati ?

And a couple of extra characters

I learnt to ride on a Honda Steppy
when I was about 8 or 9 I had a XL100 afterwards, I had a CB350 race bike in my teens and later I bought the Husaberg 501 then I inherited a A10
but other than that this is my only 4 stroke. (and of course if you exclude the other bike I bought at the same time.)

I assume what's there is the survivor of a crash which wrote off the OE cosmetics.

Certainly as described, ticks all the wrong boxes.

Yip it appears to have an early monster Front end and asemetric wheel.
story goes someone (maybe him) borrowed their dads bike and put it in a ditch 10 minutes later.
Then started this and ran out of talent or interest.
It runs and rolls.Plus the price was right.

So did it start life as an ST4? 916?

It certainly did, but it will end life something quite different.
If you want the seat you will have to fist fight Henry for it:corn:

[Kickaha]

You're a sick sick man, I wasn't ever fussed on the ST series, always like the mid-nineties SS, but then rode them practically back-to-back, ST had far better touring capability than the SS, being dodgy Italian rubbish the stator lasted until I was 85 km from home coming back from a lap of the passes and running on the battery it lasted for another 65km before doing the last 20km in van

[husaberg]

The more observant will have noticed the Dogcati has the mid 90's on steel centered discs.
The round centered discs as well as being a bit ugly, They are also very heavy. As the carriers made of steel.
355206

Because Lighter discs are so much better for touring of course.


whilst I would rather have snowflake gold inners with cast iron rotors .
As below but .....$$$$$$$

That's all part of the Italian bike experience.
The thing most people miss with the st series is that its true beauty lies within.
Time to fess up though ,you want to bid on that seat..

Having owned a 1982 Darmah and a 1985 MHR Mille I don't even consider any Ducati with belt driven cams a "real Ducati" (maybe the F1 750 gets a pass)

[diesel pig]

I looked to see what this was about but it is just another Rubber-band Ducati. pretty of them about, you should get a bevel drive MHR Mille to waste your time on, Like a poor bastard I know.

Everyone knows belt drives are the "duck's guts,"
I have one of these roadranger switch's already and I’m not scared to use it.

Now if I were using a Ducati parallel twin, I’d expect the hate brigade to show up—but shit this is a st4 street fighter with a brown seat and a Led light do you guys even have hipster beards and man buns?




Remember when Hailwood won the TT on that old 900 bevel in 78 ? this happened as he felt right at home! as he was used to riding old fashioned bikes from the 60's and not brown seated pieces of urban art, But honestly, aside from the early bevel 750 and 900SS, I find the later bevels about as attractive as a brick. Let’s embrace the future—belt drives make cool noises!

[sugilite]

I will put the seat away for you.

but without the brown leather tape "handgrips" and the go fast nascar exhaust wrap its just looks miles too far away from "Cafe' chic"

The unfortunate problem with belt drive cams is that they don't stay where you timed them.

I remember listening to a whinge from Dick Hurdeman about it. He'd put a strobe on the cam pulley and watched the timing move as the engine was revved.
There is a certain elasticity to those belts which you can do nothing about.
Except allow generous valve to piston clearances....

Many years back a 450 Duc from Oz came to a Sound of Thunder billed as the worlds fastest 450 Duc. It had a pantah head grafted on and was tuned
by the then leading OZ Ducati guys.
Mark Taylor on a bevel 450 beat it at Ruapuna -then travelled to Oz and repeated the dose at Oran Park.
And yes, i may have been involved with that one.

I totally agree as evidenced by the later ducatis using spur drives like a rc30 or other kit kawsakis in the 90's
But the Dogcati is only a buget touring bike.
Also belt drive ducatis won heck knows how many more races than any bevel as people still needed to be able to afford to buy the homolgation bike.
Ducati stopped the bevel bikes as well as being heavy old and slow they were to expensive and time consuming to manufacture.
If the dogcati needs to go faster I can always wrap the exhaust or paint it red. although added the weight of the paint ......

[Grumph]

Ducati stopped the bevel bikes as well as being heavy old and slow they were to expensive and time consuming to manufacture.

The 450 had two complete crankcase/gearbox assemblies. Both with Carillo style rods and a locally made 2nd gear pair.
Shimming and setting those up from scratch was not a 5minute job....

The 750 bevels whan they came out were at the light end of what was on the market and in
the context of the period they weren't slow.

Yes but by the time that the 650sl had come along they were lighter smaller and nearly as fast. let alone the f1750. Heck The 750 paso was nearly as fast.


That 450 with the belt drive head must have had reversed cam direction, I remember they had to do that with RV1 alchemy.


On the Dogcati with only exhaust and minor injection/intake mods plus setting cams and squish, I expect to net 120HP perfect for mild fast touring I intend to do with the Dogcati. Plus some exhaust wrap and brown handgrips and brass rearview mirrors.


A second purchase below, even at half the original cost, it's perfect for fast touring on a gentleman's sports tourer.


With a different threaded nut, these fit almost all belt twins and V4s


355208355207
As well as being a slipper, these cluches are 48 inner teeth to spread the load.
They also have a lightweight hub.

Variable Valve Timing! Swish.

[Grumph]

Variable Valve Timing! Swish.

Unplanned however.

I've never been entirely sure the Britten valvetrain problems were from inadequate head drainage.
The official story was that the cam folower buckets were hydraulicing and it would break belts
or hit valves - the sequence was never established afaik.

I suspect they simply didn't appreciate how much the valve to piston clearance changed
as the cam timing moved.

Must ask Rob Selby next time I see him.

my understanding was as it had one belt it had too many changes in direction in the original set ups
the first ones that were sold had an update to have two separate shorter belts one per bank.
less turns and less wanting to straighten out like a chain. That was the theory I heard?


355245355246

(Jim Hunter?)
Pretty sure its in the Sports rider article?
Funny enough with the inaccurate belt vs gear I remember flettner spoke of a system that used this factor as a form of variable timing.

To my mind belt allow a lighter simpler engine esp compared to gears.
Chains are not the answer either as we are struggling to get 5 hours out of the motards cam chain.

What, are you intending to bore it out to 1400?

You need to raise your bid on that seat Dave....
355247355248
ps As its a touring bike so it only needs to go to 916cc
As they as std do 55mpg at 100MPH.
I am thinking of some pod filters though. but I think I will go with a big arse car one and big arse bell mouths
I have however ordered 2 different power bands off the internet though.

Cheers that encouragement might help raise your bid on that seat.
TBH I assumed the seat was an off the self Cafe' seat (and maybe it's is based on one) but its pure Custom fiited to the docati and even was retained by a solid brass fastener That looked like it same from a old folder or set of drawers or something. So it's completely one of a kind.

I do intend at some stage running a live Auction for it. Especially considering its now gone international on KB.
I plan to have a wee play with dogcati this weekend and slowly strip away some more of that CAFE/Streetfighter/Bobber Patina.

I once striped down a RD250 once that has a race seat sheaved in actually house carpet. it had race numbers and all and weighed a ton from all the bog/paper mache. But someone once loved it. just like the Dogcati.
This project has a time limit though.

Whilst it would be cool to put these on, I am saving them for another project.
These are for some the holy grail 4v Ducati rotor fully floating cast iron gen brembo.
Although personally even I think they are OTT for an "st s4orts tourer"
355254
But without the "brownseat" it does need to have something special

[husaberg]

I started stripping down the Dogcati on the weekend.
I found some good some bad.
The ST4 has a truly tiny airbox, The header Pipes why they may look cool have been modified and might need some remedial work.
St4's whilst not having a flash spaghetti style race exhaust are a performance mod for 851/888's.
355322

https://www.bikeboy.org/888st4ex.html

I found the rear master and a lot of other missing parts in the spares box.
I also solved why the front brake was so shit, the lever was hitting the throttle. I am glad I resisted the urge to take it for a drive especially after I noticed the chain running out of line.
the throttle is a two handful job but I am pretty sure I can move the pivot to shorten the throw.


I am a bit undecided what to do with the wheels as it has a early front with a mismatched late rear.
I do kind of like the early wheels but they are heavier than the later and the late ones are heavy.
Anyone out there with Any Ducati three spoke wheels or Yamaha FZR 3.5x17 and 5.5x17.
355261
Early
355260
Late

for reference below is a 89 FZR1000 these ran the same pattern discs.
I assume due to the association with Cagiva/ducati and Yamaha brembo at the same time
I do prefer white wheels as I guess that's what Ducatis and most other bikes had when I was young and impressionable.

I do like Dymags but the works ducatis tended to run Marvics:2thumbsup
https://www.marvic.it/en/prodotto/vintage-streamline/
355264
they make them again but they are unfortunately outside the budget especially considering the Dogcati was a 2k bike. With a total 5k Budget.The Marvic wheels themselves are about that in USD
So I will settle for some stickers that say Marvic.
I seem to remember thats about what the cost in the 90's



i did find very interesting mod though, the Battery on the DOgati Streetfighter conversion which was tucked under the brown seat was found to have a rather innovative method of securing it.
Double sided tape.
as I like
the 851/916 positioning

Ducati electrics tend to have a certain reputation, so having it accessable the beside of the engine might be more practical
Not sure where the ST4 has its std but I thought the monster had it under the tank?

M unit and CAN bus.

I should be able to tell you where the battery is on an early Monster as I owned one. Under the seat I think?

on the 1100 monster it was under the air box up top because I was going to put a battery tender lead on it and you basically had to pull half the thing to bits to get to it.

I am lusting after Ducatis again. Theres been a Desert Sled X thingy parked outside work for the last two days and its way cooler than the Husqvarna but also literally three times the price.

One of the coolest things about Ducati's is even the doggiest ones are dead sexy. They are also compared to say a CBR600rr or YZ450F, pretty dam user friendly to work on.
The only thing that's frustrating is the weight of the thing without front and rear stands.
I have had a bit of extra money a few times over the last 10 years years and each time i have talked myself out of a 916/996.
i thought it was silly as i would likely splatter myself all over the road/truck bonnet.
But now i think i have kind of caught the "Ducati bug" and i think the only cure is get a real 916 /996/998 sometime soon.
That desert Ducati thing does looks kind of cool in yellow and white.

[Kickaha]

Mid nineties the batteries were up under the tank, the side mounted battery isn't as accessible as you may think with stock fairings anyway on the ST2, not sure about the ST3/4

Assuming the ST4 is the same as the ST2, it's in a plastic frame hanging on the right side of the frame beside the engine.

Super winning design, requires removal of the mirrors, upper fairing and both right side fairings to change it.

AGM battery under the seat is probably the only way to make it disappear.

355265

Wait a few years (likely anyway). Whatever comes after Lithium will be small enough to mount as handlebar ends.:woohoo:

And hopefully not be a fire risk with dooklattery electrics. ;)

Cheers, I had an inkling of them being there, but looks like when they stopped the previous carb side by side, for fuel injection with the throttle bodies spread apart in the V, As they never had the room. Especially with a bike like the ST that was meant to be a sports tourer with a decent size tank unlike the city poser Monster. they also need a larger airbox as even the st4 one is tiny and they seem far bigger than the carb monster ones.
Now it makes makes sense now how bulbous those monster tanks were as a result plus how tiny the airbox was on them.

however I found some of these at Mums the other day, I am pretty sure they are 1950-60's racing push bike water bottles.
JB did something similar on the V1000 although I think his were spraypainting pots stolen from Bob Brookland. So its legit big twin tech.
355298355281

In-spite of everyone's obvious deep seated love for the Brown seat, The seat I intend to use will not have the room.
I will I guess have to sort a way of making the non ST fairing QD. plus I will have some remote cables if needed.



Ahhhh, the eighties - I loved looking at the white wheels. :love:

I really like that white wheels and red look of the early to mid 90s Ducatis.
There is one year I like the colour of, they seemed (like Ferrari )to change the Rosso red every year. I like the slightly "oranger "of the reds.
looks like arround 1991 same with the Decal font.
355268

[husaberg]

I mentioned earlier the Dogcati has a mismatched front wheel
I was talking to one of the better humans the world has Andy at https://www.ducatispares.co.nz/
or https://www.facebook.com/Ducatispares.co.nz

I asked him about the wheel I said it was a bit odd looking and it looked like the bearings had been changed and guess what......
It seems the bearing were changed to get the early wheel to suit the 25mm late axel forks but these 47x25x12 thus are thinner then the original 17m axel 47x17x14mm or 47x20x14mm
No real issue...as long as the spacer is made to suit, but what the fuck is the silicon for......


355293

On the plus side as well as lots of great advice and new consumables and other really cool stuff, Andy had the 916 S4 alloy rear swingarm.
The early monsters had a short alloy arm as did the 851/888, but the ST4 is steel and a little longer the ST4S and some ST3's had an Longer Alloy arm.

I'd found the paint pots when I built the 500 Kawa. All catch bottles had to be fire resistant. New reg at the time.
Told JB when I worked there. Pretty sure he went and charged them to Bob's account.

I do enjoy getting courier parcels these days.
This came from one of the planets better humans Andy from Ducatispares
https://www.ducatispares.co.nz/
https://www.facebook.com/Ducatispares.co.nz

The S4 swingarms I different from the ST4 in that its made of aluminium.
Which whilst its lowers the unsprung weight (remember over 50% of a swingarm is unsprung).
This is of course of great importance on a touring bike.
The swingarm is potentially also able to be shined up to a decent gloss. which satisfy the magpie urge to have cool shiny stuff
Hopefully distracting from the poo brown seat on the Dogcati.
355318355317
Andy being a metzler agent, was also able to order some metzler tires on indent with a pair also for the supermotard for the Burt.
Metzler in my opinion ,offer grippy tiires at decent affordable prices. They wear well while not as well as Michelin do, they are 1/2 the initial price.

[husaberg]

The Dogcati continues.......
Well the Dogcati came with open pipes there in the spares piles are some very heavy and exceedingly fugly OEM heavy oval pipes.
Knowing that all great Ducatis have Contis if they are pre war (Iraq)
or if they are post stone age they have to have Termignoni's
https://www.carbon4us.com/105104-home_default/3d-special-aluminum-sticker-for-termignoni-exhaust-90x90mm.jpg

As the budget came up a little short as the Motard needs tires for the Burt as well as full top end rebuild (yes another one)
We have compromise a little to settle for a more budget approach.
The Termignoni's will have to wait, I was going to make my own but these are to cheap to even bother.
they are listed variously as sakrapovic which I assume is a cross between scorpion and akrapovic.
I also brought some pretty cheeky stickers Togo with them.
I am guessing the quality will be a little down on the east European originals. Or the Italian ones I so covert.
they claim to be carbon I feel they might be more carbon steel.
355341

Also seeing as the Ducati 916's are able to do 60MPG at 100 MPG. I have decided I can get rid of the std ugly tank in favour of something more Ducati beautifull.
So from the same country far far east I have brought one of these 10 liters should be ample for a gentleman's tourer.
355340

[F5 Dave]

A gentleman who doesn't leave the city! That will suck goats. Current trend to reduce tank size is going to stop me upgrading, but 10, or let's say 8 before you panic will limit you every ride, good thing you don't live where there's decent gaps between stations.

I am not sure you are getting the whole Italian Ducati cafe racer lifestyle. 10 liters is way far enough between cappuccinos. Especially with clip on's and thinly padded seats.
I thought you Wellingtons were generally pretty evolved like that.

Remember by making the fuel tank smaller ,I can make the Airbox far far larger, the fuel tank is taking one for the team.
Have you seen how ugly the std tank is on the ST4, I am doing it a favour.:rolleyes:

Get another box like that and put it in the seat hump with an auxilliary fuel pump up to the "top" tank.... then you' d have two fillers and 20l capacity!

Easily, mine ran for 19-1/2 hours to cover 1600km straight on more than one occasion, but it was the superior bevel gear design, I don't know that those flimsy rubber bands last that long

Yes thst is Fugly, granted, but what about [spitballs] a ZX9 tank or of that ilk. Conventional yet not desirable so not expensive.

Clip-ons and thin seat? Harden up! You're talking to the wrong audience. I did enough 2hrs and GPs folded up on a bike 2 sizes too small sitting on fiberglass to be sympathetic.

I like the hover pipes but maybe trough the frame rails like one of these
Those OW01 and ZXR were a bit obvious, the Italian like more Coke bottle feminine lines rather then hosiery jutting out.

Looking at that airbox and the gaping bellmouths reminded me of a cautionary Ducati story.

Check the underside of the tank that forms the airbox roof.
916's at least, have something bolted to that bit of the tank...

At least one 916 in ChCh suffered some very expensive head damage when it swallowed a nut...

I'd also point out that big airbox hoses could be moved to serve as snorkels in West Coast weather.
Could be useful with the weather extremes we're seeing.

Roller bearing, 1982 Darmah, did that 1000 mile run twice on it, small tanks suck balls, had to gas up every 160 km, did 50,000km + on that bike, the V2 big end did fail on it about 12k after I got it but they replaced under warranty and no other problems after that

The Mille didn't do a big end but it did drop a valve due to some incompetent monkey not assembling shit correctly

I intend to have All the air going to be filtered to the box. for belts and braces.
I have an idea to have a real top clipped on much like a std.
the feed will be more cold air than ram air. it will also have a downhill kink to run any pooled water out.
Oddly enough after years of running uni foam filters out in the open I never remember any issues with them getting wet.
there is an option to do something like this for belts and braces. That way the seal on the tank doesn't have to be perfect.
I want to have it so the hot air from the rad and engine dont get breathed into the Engine.

RS125 are made for tiny Japanese. I raised the seat 50mm and dropped the pegs the same.
And I'm taller than you.

Just today I made an extension on a ride because I could. Got to 309km, computer said I had 7km left but put 15l into a 17.3l tank so more left for sure.
Would kick a moddified Dooklattery for economy by a margin I bet.

[husaberg]

I tried the FZR250 tank, its too narrow across the width at the front, but looks better than it should.
The fzr250 tank came from Greg.
It could be made to work with the std airbox with a bit of hammer work.

This is what I need though a FZR400

I am not expecting great durability but if they last a few days in late Feb I will be happy.

It's like Xmas....:innocent:


I do enjoy getting courier parcels these days.
This came from one of the planets better humans Andy from Ducatispares
https://www.ducatispares.co.nz/
https://www.facebook.com/Ducatispares.co.nz

Andy being a metzler agent, was also able to order some metzler tires on indent.
Metzler in my opinion ,offer grippy tires at decent affordable prices. They wear well while not as well as Michelin do, they are 1/2 the initial price.
They are round and black and in 120 and 180 sizes so suit the 3.5 and 5.5 rims.
They are are Metzler racetec's. Which to my mind offer the best performance vs cost.

[Hairymcsweary]

I have 2 early model FZR 400. They both have box tanks with covers. The SP cover is alumium or similar and is a full cover and the standard is a plastic cover with a cut out at the rear for the seat. I have a spare box tank but no spare cover.

oh okay what are the dimensions of the box tank? 15liters...

[Hairymcsweary]

Yes 15 litres but 5 of those are where your rear cylinder is. The FZR tank sits in the frame with the top 10 litres under the cover and the rest of the area used by the airbox. It would take a fair bit of fabrication to get it to work for your application.
Apologies if picture files are too large.

fair enough unlike to work as it has to sit on top of the cylinder
the 10 tr tank never arrived i will have to follow up.
The cover shape though looks great at the front though
Can you please do a rough measure? of that original drawing i might try and find one.

[Hairymcsweary]

The measurements are the same for both the SP cover and the standard. If you are looking at wreckers - GP have 2 they are wrecking. Make sure you dont pick a model where you see the seat come up the tank as in the photo below because there is a void that will be visible on your bike.
A= 180mm
B= 380mm
C= 380mm to centre of hole
D= 260mm to centre of hole

Thank you very much ,most appreciated
The Alloy reservoir arrived today, its actually bigger than i thought.
I might have to lie it down.
It's quite refreshing to have posts about Motorbikes on the site away from the ESE thread.
It appears very well made too, At least with the welding anyway.

[husaberg]

Well not much happened on the Dogcati this weekend
I faffed about a bit trying to figure out how to make the airbox and the fuel tank live together and breath.
at this stage I am going to make the Airbox a heck of a lot bigger or 2x the size breath through the air intake from the front at the sides of the airbox like a 851 and 916 hybrid.
I think I am going to cut and shut a couple of airboxs and lids and join them together. With two front sections. which have a taller lid.
to give me more space for an airbox I am stealing area towards the steering head and removing the pleated air filter on top in favour of smaller pleated covers from ram air vents/snorkels in the front like a OW01 or KAwasaki ZXR750 or Ducati 851.
I will post a couple of pics to give a idea. but my description if pretty shit.
355479355480355481

the first pic I'd I think a 998 the other two are modded monster?s ????
I better start sorting shit is the deadline is about the 22nd Feb in time for the SOT.

[husaberg]

After some googling at lunch I decided to go with a S4r airbox, its ordered and on its way.
Andy at Ducati spares had one and it will be here before the end of the week.
this should fit (I hope) if it doesn't well I might have to use a Monster frame.:bleh:
early monster frames and st4 are similar to the 851/888 but different with how he subframe the and the steering head are braced. (Plus the rear suspension)
That said It is a lot better shape and It has a bigger volume more aesthetic shape.
The filter size goes up from 210mmx210mm to 217mmx278mm so that's abox 25% larger so the box is at least that is not more bigger.
Plus it doesn't effectively block off the air entry into the Bellmouth with a lip a few mm above.

355490355495355496
some pics here I want I intend to do plus the pics of the st4 vs S4R airbox


With the std st4 for instance below the front intake is not even under the air filter as it stops short of there, it has a ledge about 40mm high to the top of the box.
look below and you will see what I mean.
355491355492

Oh i can already hear the wtf why go to the trouble do this, but anyone familiar with this era Ducatis will know they have shithouse airbox's and like Harleys of the area they used The airbox to control the noise.
The std intake with the top off is good for 118 with better ex and the cams dialled, but I want 145 HP and 145kg
I have a early 2001 Husaberg which breathes right next to your nuts ,Intake noise can be intoxicating.
At this stage I am not sure if I are going to cut the top off and run the std filter or do the snorkels into the side like the 998 or what ever it is in the pics with another cold air intake through the top like a std S4r.
All i know its bigger , in this but not all cases bigger is better and I have not seen a thread when I searched where someone has done it.
pics to follow...

[F5 Dave]

Having just used a jack and portapak on the Stinger tank to get it to fit the frame again, I'm sure you could just open the frame up a bit to fit the airbox. Have a welding torch and a few bits of water pipeline handy to fill in any gaps. ;)

Yes there's a bit of room.

[husaberg]

The bigger S4R airbox arrived (well at least the lower half anyway.)
This came from Andy at Ducati spares.
https://www.ducatispares.co.nz/
https://www.facebook.com/Ducatispares.co.nz
IMO he's one of the most decent humans ever, he knows these bikes inside and out snd has so many spares he hasn't got enough time to put them all on the net. He's also an endless source of knowledge on how to improve these bikes and what's worth doing and what's not.




I can pick up the rest during "Burt week "in a few weeks when I am down that way.
the S4R set up appears so much better and efficient it's not even funny, it has to be worth at least 0.25hp alone.;)




As the ST4 Dogcati was somewhat hacked/chewed about when I got it.
I never knew how the std headlight bracket worked or what it looked like. As it was not was in in the extensive spares boxes that came with the dogacati.


I knew it was a complex bracket supporting an ugly headlight especially compared to the 851/888 or monster or 9156 cats eyes.
but who knew it was an alloy set up actually had a pretty flash air scoop reminiscent of the carbon fiber 888 course scoop
If I can find a ST2/3/4 headlight surround it looks like I can modify it to do what I want for the dogcati fast tourer.


Below is the ST2/3/4 headlight scoop bracket set up
The bottom scoop splits on into two and it seems feeds direct into the trumpets that come out of the std ST4 airbox. (If you are confused so the pics in the post before this. bottom left first attachment)
I can of course it seems drill a hole to insert these in the S4R airbox (Cool aye)
355517355518355519


the ST4 scoop might not work but I intend to replicate its setup anyway. I will just augment it with side scoops like a 851.
Obviously, the headlight and upper support will go as the headlight and standard fairing are some of the ugliest things ever put on a Ducati. (maybe other then Kickaha):whistle:
Is anyone here familiar with the St scoop bracket is it super heavy as it looks like two bolt-together cast alloy pieces?




I am still looking at doing additional side scoops direct to the airbox like a 999 OW01 ZXR750 999 etc as in the second pic in the post above middle lower layer.
but I want to combine the st4 set up as well.
so at this stage I am having side slits like a 851 with a hozozonal slit under like a paso. (or some models of 900ss which used it to feed the oil Cooler (much like a Trident rocket three F750 racer letterbox for Grump ;) )
355522355523355524
Note the 851 std road going model also, has this slit as its forms part of the headlight surround. I think I have posted pics already. Okay maybe not on this thread.




We have taken on board Dave's concerns I believe we have came up with a way of mitigating the lack of range, with the smaller fuel capacity.
More on this later....:2thumbsup

My son just had to made by a mate , As the we are taking the CBR as well as the Motard to the Burt. Currently One signboard sheet short, plus a few other details Like ply for the ramp, storage for gear and stuff at the front. but close to finished.
It offers more creature comforts and wind protection than a goldwing fairing. Si it's just the thing for a gentleman's sports tourer.


As I mentioned re the ST series it as std has Ducati's if not the world world's ugliest headlamp fairing combo. We are doing something different with the fairing as I still want protection from Canterbury's Nor'westers. and I am not a fan of the french inspired 1990's street fighter look.
this is the std ST series.

355530355529
We intend to do something like this. Mixed with this
355531355533
which is in keeping with Ducatis sporting Past

[husaberg]

Installed the airbox bottom tray, a couple of differences had to add what looks like a temp probe and there was a mount under their for some some electrical gublin, that now just flaps around with all the other spaghetti.

355536

The pics below should illustrate the thought process that lead to the airbox swap.


355537355538

I also went through all the parts and sorted out the chain run. I am definitely going to have to make the alloy tank smallererer.
355539355534

One thing I did find is the rear suspension is comp and rebound adjustable I had never seen the rear reservoir previously.:o

[F5 Dave]

Maybe a periscope to see over the top of it?

[husaberg]

Maybe a periscope to see over the top of it?

Yeah On reflection I think I measured from the frame rail and not the cylinder head pokey out bits.
but on these are bike you sit in them rather than perched on them like a modern bike
Here is the std st4 tank for reference.
355549355550
regardless it will provide the basis for the tank and it was cheaper then buying the sheet and the fittings.
I was talking to one of the Stainless welder /fabricators at work he seemed keen to help for beer tokens.

you have to admit though that airbox especially now you can see the bellmouths is kind of cool
Speaking of which the Ducati airbox securing system is kind of cool.
On my one the front bolt goes into a rubber bung its probably meant to bolt through from under nead but with a smaller head on the bolt it just slips with a hole.
The rear two sits on those funny bolt pedestals but it seals through twisting the bellmouths which engages a set of pins and pulls down the bellmouth until it seats the rubber bellow and o-ring under the Bellmouth. which is bloody neat engineering.
So to remove the whole air box it only takes a few minutes not like my sons CBR600RR with is a hour at least to get near the throttle cable with everything bolts and multiple screws and seals.

I can remember the bike vaughly, how did he get it in with cylinder Reed I thought that was why you went case Reed on the non honda?

but the Dogcati is definitely having a cover. a curvaceous voluptuous shape at that.
funny enough I have this but because its essentially irreplaceable. One of about 400 made.
these is no way I would use it for fast touring.
355583355584

But even if I wanted to now what with the airbox being a few mm wider it will no anyway.
So I am making a cover based on this shape. Well someone who is great at fibreglass is....
to be brutally honest I think there is a case for Norton JPS style pannier tanks.
I could get a full fibreglass tank, but I was standing on this corner, right in front of the bike when this happened, It put me off them for life.

I built mine about a decade before his but the mincer I used to do the welding of the barrel and cases just kept trying to fix his mistakes and the aluminum was separated from the steel liner. It was a brand new nos barrel I'd got for $85, but it was irreplaceable. Felt so despondent I wheeled it under the house for many years. When I first built it it was a generation ahead of anything else out there yet to an old school bucket budget.

I think his had a tiny carb on it.

Care package arrived from Andy at Ducatispares

https://www.ducatispares.co.nz/
https://www.facebook.com/Ducatispares.co.nz

Seals for front and rear calipers and Master Cylinders.
I already had a new std style front lever and some new reservoirs
Cam Belts
14T Sprocket as they only put a 15T on them to pass the drive by noise test.
When the chain on it gets worn I will do 520 chain conversion.


Engine breather is Alloy as the plastic ones tend to break.

Oil filter
Air filter (SR4)
Quick action Throttle
New Throttle cable. as the Dogcati currently has a twin cable very slow action one of a Carby Monster.
Bar grips.

New oil pressure sender as these can let go releasing all the oil in the process. (in time I intend to run a braided line frome the sender to the cams as this gets oil quicker to the fragile rockers.
Plus arrived quick all at bloody decent prices.

Andy also found a SR4/s2r airbox lid for me
355609355610
One weird thing with the Airbox lid above.
It looks like some sort resonant chamber or an intake silencer baffle
any ideas?
(I have lite it it from underneath hence the light at the end)

355611

Hes also found me a moth eaten ratty ST4 tank I am intending to chop up into a dummy tank

I mocked up some Daytona rear sets off my old bucket but the original bracket places the pegs a touch too far forward..
So I will need to find some alloy plate.
355613

I have also had a bit of a poke around and I think I can directly substitute the later coil on plug set up in place of the std coil packs
That way I might be able to tidy up some of the massive rat's nest of wiring.

I can't reply to your message, your inbox must be full. This is the bike I'll be using in the hill climb and sprints at the Burt. Unsure of year all I know is its pre 89. Bike belongs to Butch Woods, he bought it as a parts bike and decided it was too good to wreck. He did nothing with it for more than a year and then he decided to let me give it a run at the Southern Classic last Nov. He enjoyed seeing it run after we sorted a couple of comical issues which I'll share with you in person, and is keen for me to keep racing it. It's an ex Andy from Ducatis Spares bike and used to be owned/raced by a guy called Gary who loved running at the back of the pack.

He enjoyed seeing it run after we sorted a couple of comical issues which I'll share with you in person, and is keen for me to keep racing it. It's an ex Andy from Ducatis Spares bike and used to be owned/raced by a guy called Gary who loved running at the back of the pack.

Butch can be pretty entertaining at prize givings.
Pre 89 is such a cool class.

re the box i had emptied it the other day but yeah it might be full.
Ducatis are a cool bike and they are what I feel is a "formula kit bike" what you do is well known to get them faster or handle better lots of parts can be improved or swapped and knowledge is freely available plus you can do a bit as you go and as budget allows. Also of course for a 4t the sound can be glorious.
I am glad glad the pre 89 rules allow a slipper clutch, those pre 82 ones don't .Although raising the idle can help.

oh yeah did nothing on the Dogcati.

[husaberg]

Good to meet you in person Hairy, and to Catch up with Eddie
We took the Dogcati to the Burt I was planning on getting some help with the Cams but run out of time .
I guess the cats out of the bag that the Dogcati is transitioning into a race bike..
The fairings and tank are not finished so it won't make the SOT, but that's life.

[husaberg]

I haven't been busy but others have.
My Fiberglass guy is making good progress the fairing and seat and tank cover.

Hopefully it will be ready next week as we are over in CHCH racing sat and Sunday, so we can detour down to pick them up. Sat night.
Dave uses one mold for road 851 and race 851 So all race fairing start with indicators and headlights.
I am just grateful there are still artisan people with these molds in NZ, as ducati only made 5000 851/888. Which I think is how many Honda made of the RC30.
He's even going to make me a the TZ tank for my other stalled RD/TZ project
He's going to add in the lower slot so I can use the st4 intake I just got off Andy so I can have 3 air feeds to the Airbox not for ram but to allow decent cold airflow

I got a larger bonus than expected So i have been able to buy some extra stuff for the Dogcati ahead of schedule and I don't need to sell my kidneys to pay for the fibreglass work.
So thanks to Andy at Ducati Spares (https://www.ducatispares.co.nz/)

For the Dogcati I ordered some lightweight adjustable pulleys in anodized Egral 7075
https://www.ducatispares.co.nz/products/adjustable-cam-pullies

The Dogcati needs these, as no Ducati is timed anywhere It needs to be std let alone to make it suitable for racing.
Some reading here and here on Ducati cams and timing.

Andy also had the proper side mounted battery box for the ST4 which is similar to the 851 set up.
i have the timing tool so i can lock the pulleys in place to change the std pulleys on my 851

Andy is constantly adding new stock to his website (https://www.ducatispares.co.nz/) and is able to source stuff at great prices for bike not luck enough to be born Ducatis as well

For instance high quality US made carbon pads and quality Italian Newfren clutch plates we just got for the CBR600rr At bloody decent prices
He also sponsors a shit load of racers in the South Island.

I like this thread. I want another Ducati now

[husaberg]

I have been scheming on how I am going to do the breather system.
Ducatis being a 90 degree twin fire 90 degrees apart then a gap of 630 degrees to the next firing they move a lot of air under there pistons as well as above and this windage costs power so they are not much better then either a a old pommy 360 crank or a single.
So they require careful attention to the breather system to make power at high revs and keep their oil intal to the engine.
Ducati breather with the plastic breather and the Reed built in are known to be inefficient and a weak link, when a plastic one lets go, it has a habit to directly oil the rear tire.
Same with the oil pressure sender (as Laava and any others before him) recently found out

What I plan to do is increase the diameter of the breather 2 piece CNC breather I have from 20mm ish to 25mm an then have my own version of the corse 888 and 748 system
this goes under the seat and has a 25mm entry at the bottom and a 22mm exit at the top which goes to the airbox where it will breath through a 4 petal 2 stroke Reed valve from a chainsaw/RC plane.
355786355789
It's meant to be worth about 3 hp at high revs and also makes sure all the oil gets returned to the crankcase. So none ends up in intake or the rear wheel
I was thinking I should be creating a seperate system with vacuum like the late indycars with a vacuum pump ,or the vacuum from the ex pipes .but TBH that seems OTT, KISS wins.
The other benefit is if the bike blows up internally the oil gets blown into the breather tank which doubles as a catch tank.


I intend that it will look like his only likely less carbon to a start off. It took me a bit of figuring out but the breather 1'' from the engine goes into the bottom the outlet tube at the top 3/4''goes to the Reed in the Airbox.

I like this thread. I want another Ducati now
Treat yourself Enry...
Cheers it a refreshing change to have bike stuff on KB outside a few threads.
Plus there are only so many times you can engage with stupid people saying increasingly stupid stuff.
Especially those where they seem to be deluded enough to Dunning Kruger themselves into believing as they read a blog they know more than actually medical and scientific experts do.

Anyway a guy I work with is doing up a 860 darmah, every bill he gets for the guy doing the work is 5k.:eek5:
I am sure it will be beautiful but it's still an old darmah LOL.
I am not sure, but my where my total budget is at atm , but that was meant to be my total including buying the thing .. but like all race bikes, it will evolve over time.
Plus I am terrible at maths sometimes:msn-wink:

Ducatis need not be expensive 916 and 748 749 and 999 are still reasonably affordable, st4 and ST4s are criminally cheap and very usable and improvable. Plus are so gorgeous look at and to hear.(pretty applies to 748 and 916 not ST's)
There was a pretty cool older 750SS for sale the other day.the boxy 89 styling and colours with a later USD front end looked very cool.
That would have been a great Sunday afternoon and town bike.

I was looking at a Husky 701 the other day it was a pretty low seat (for those shorter than av) and it does a indicated 220kph at Ruapuna stock. so fast enough to still not be boring. they probably will be doing deals at the moment.....

[Kickaha]

Hopefully it will be ready next week as we are over in CHCH racing sat and Sunday.

Fuck I forgot about you, I went out there Friday just to have a look at Daniel's BMW, which was very second hand by the end of practice

No you don't

An engine alone is an easy 5k+, don't ask me how I know ;)

They called a 900 Darmah (yes I know they're really only a 860)


A lot more beautiful than that belt drive rubbish (with the exception of the F1)

We are over this week coming for Cams and MCI. Just with the F2 Honda though.
The Motard is still waiting for its new extended water pump shaft.

To tell you the truth they are called a SD or SSD900
I never figured out what the SD stood for the SS GT ST MHR all make sense...
I would rate the 851 in race trim as pretty as an F1, but neither hold a candle to a TTF2.

PS the MHR was ugly as was the S2. Only now is the SD900 is growing on me, after what 40 plus years later.
The GT750 and 750SS and 900SS and late 250/450 were the lookers.


Anyway I doubt we will agree, so I did the quick math today I am only 15% above budget with some judicious creative accounting...
Go try and build a bevel race bike as competitive as that in its post classic race class as a Corse spec pre 89 916/851.
plus the 916 851 has a glorious sound all of its own.

It should look like this only with less carbon and mag and far fewer corse bits of course for a start off.
but it needs the white wheels

355839355796355797355798355799355800



Whilst it won't worry a decent FZR1000 at Ruapuna or Teretonga I think it will put the fear of God in them at Levels Greymouth and Whanganui.
With enough $$$ I think I can achieve 145KG and 145 HP.
On the other hand I can't see a race spec F1 worrying a XR69 at most tracks aside from street races. Not to mention pre 82 cant run slippers unless the had them from new or were a period mod ala ELR or FWS or nr500 or probably CB900F

[Kickaha]

The S2 was, the MHR was fucking gorgeous https://www.kiwibiker.co.nz/forums/showthread.php/80887-La-Bella-Italiano?highlight=bella+italiano




Anyway I doubt we will agree, We won't, mostly because you are wrong and no 851 will ever sound better than a bevel on contis

I'm actually heading to the coast but might be back for the weekend, if I remember I will callout to the track

The Gooldie bag arrived from Ducatispares (https://www.ducatispares.co.nz/)

The pulleys are so light and so beautiful they are worth it simply to look at them.
355852
The air intake is way lighter then i expected, a credit to modern thin casting techniques and judging off how it look on my 851 should work well on the Dogcati with the 851 fairing.


355849355850
its also mag treatment (chromate) colour
The couple of race bikes under the Ducati spares banner (https://www.ducatispares.co.nz/blogs/news/inappropriate-racebike-part-1)also retain the scoop as Andy mentioned it is where the rectifier/reg is positioned so its a great heat sink with the cool air..
Plus its a good place to mount the number board.


If I was building a race bike I would use the std early pattern Ducati grips not mater what make it was as they are very cool. (Plus at $20 cheap as chips)
355851


The battery box is close enough to the original, actually not 100% sure where the tricolour had there's but the 1989-90 had it next to engine of the side like the later ST4 and 916.

355853355854 pic is an ex Roche Corse f89

Not arrived yet, but on their way.
I also brought a used pair of later pattern 3 spoke wheels at a decent price (from guess where (https://www.ducatispares.co.nz/))
They are later pattern are the same as the front 3 spoke 916 so look marvicish if you squint hard enough.
They are not the lightest wheel, but I feel 3 spoke wheels are an important part of the pre 89 look. rules only seem to define the size 16' or larger 5.5 Max width and not be carbon.
Whilst the ultimate aim the budget certainly does not stretch to Marvics yet, I think they are 5 or 6K, but likely we'll less then 1/3 the weight.

[husaberg]

Well I know know what was in the air intake it certainly appears to be a sort of resonance silencer
complete with a spider web/nest
355898355899
355901355900
So will its removal make any noticeable difference to output? Most likely not... but who cares, out she goes..........
I will tidy up the ribs and fill in the hole.
I might end up making a spacer or another airbox top anyway.
ulltimately I will have a copy of the Corse airbox /undertray air intake.

[husaberg]

Not much happening as I am waiting for some parts for the Exhaust and the fibreglass

Before I can start the Fabrications and alterations to the frame.
The Fibreglass artist is ls making a plug for the tank mold as the one he had turned out to be 900ss Not 851......
So I am taking my original 851 tank down from this to get the shape right. The Ducati types will note the tank itself is far too valuable to risk on a race bike.
As its an unobtainium alloy tank.
355965355969355970



He did sent some pics I was "happy with the results" I mentioned the changes I wanted to make for the airbox inlets earlier
I am planting on changing the side vents to go to the side of the box and the cerebral horizontal will go to the front.

355967355968
I am going to get the fibreglass artist to make a breather box as well , Plus later on a replica Corse intake but with my own twist.


Hes also making me a TZ tank for MY RD NFP.

355966

[HenryDorsetCase]

Whats that breadbox tank (bottom photo)?

[husaberg]

Whats that breadbox tank (bottom photo)?

TZ350 rep. For My RD restomod project .
Its meant to be a like the first model TZ twin shock but with elements of newer TZs mixed in.

Fibreglass artist had no mold but modified it from a 1960-s TR250 Suzuki set up he had.

its meant to end up something like this
355979
In line with F5 jibes its the NFRD for never finished.
Its a late RD with a top end from a 350LC rad for its TZ looks
box section swingarm.
brembo 320mm disc and r6 4 pot, yoyo hub disc rear (pretty hard to find)
39mm TZR250 forks with TZ look front guard
Spoked wheels. on fat 2.5 and 3.5 x17 rims.

The forks and front rim took ages to find
As has trolling the net for all the specialist knowledge of what can be used that bolts together to look like its not modified.

[husaberg]

Anyway back to the Dogcati.
The rear brake set up is far to blah blah, even thought its a bronze brembo set up.:cool:
So in the box of bits I found a early carrier for a monster
Some monster had a underslung set up.

356001
This bracket I believe was later cut away and used for the floating set up on the SP5 and the Super lights and some various other special edition Ducatis
The early works bikes had floating set ups and I doubt it will be better than the std set up, and will likely be heavier but I believe the floating set up us worth a secs a lap on looks alone.
Note the Works bike had small 190mm disks on their Marvic rims I will have to wait for that marvic $$$$$money
I intend to mod the bracket to have a bush and bore it out to suit a larger axle and be held captive in the swingarm for easier faster wheel changes.


356000355998

355980
This above is the sp5 SSSL and monster dark and others set up.
355982
this is the special floating bracket
355999
This is the more common but still rear ish early monster under-slung which I will mod to work floating
355983355981

below is the superlight and SP5 888 set up

It's found on these bikes.

Oh yeah, Greg was going to pass it on as he didn't need it for his build. I'd sent him a couple of spare heads. Some projects don't get finished I guess.
My kicker was missing off both bikes. I got given a very nice Left hand kicker from a GT. Problem solved. Until I finally fitted the up pipes. Now it doesn't fold in. :facepalm:
