Your right about the Sidecar GP being fun, I reckon the more people who do that, the less will want to do anything else.

As for videoing, everyone is doing something toward the weekend, I don't mind contributing. Will come around tomorrow, lets talk how to get that three wheeler going faster in a straight line.;)

[TZ350]

Kel and Richard were doing the same lap times. Then Richard won. A good example that straight line speed is not everything.

True, straight line speed is not everything but sure nice to have, electrical gremlin stopped Kel.

[TZ350]

no point posting the videos seymore , not like you get a thanks for doing it apart some shit

Whos giving Seymour video shit??? Seymours videos are a hit and eagerly looked forward to....:yes:

[TZ350]

10years time when he's still winning,

310505

I will be racing a Zimmer frame by then and still not able to hang in there with the leader..... :laugh: maybe corner speed is everything.

[seymour14]

Cheers Rob, lets lighten the evening up and watch something that's not rigged...

Rigs!!!

[Grumph]

Interesting, we maybe talking more soon.
Stumbled across this yesterday A.N.D motorcycles via eurospares.
I have nearly all the bits other than the red bit linking it all together.

looking at that one, I'd lay good money on it's being heavier than mine...mine's stock frame loop with light subframe, extra crossmember up front and a ride height adjuster built in. Alloy tank and seat. Don't actually have any pics and it's well buried in the barn....

husa - RS's on both mine and Tony's. I'd already worked out the jetting for the blend on the RS's on the Budget F1 bike that Holden set lap records on everywhere we raced it. Are you referring to the article i think KB did on Tony's bike ? I never saw it but was told about it, apparently Tony told the writer to contact me but he never did.

[seymour14]

Sorry Tim, you might want several stiff drinks before watching this.

You may probably not want to watch it either, this was a tough video for me to take.

No worries, was even watching them at smoko, no matter how much I will our sidecar to go faster it just keeps coming in second...:facepalm:

[Bert]

It's been rather quite in here (actually in the entire bucket forum)...

Is this in response of the GP aftermath and/or endless sh!t given by those that aren't involved (and generally have no idea)...

Or has the winter blues started for everyone.


Mr Bucketracer and steamroller, how's your F3/superlite projects coming along?
Let's see some updated photos & maybe even post them into the Superlite register thread (in the racing section)
Are they going to be ready for the new "Bridgestone VMCC Series"?

Looking at the entry form anyone entering is going to get a lot of racing this year.
Kinda cool setup, with two race streams: longer Trophy races & sprint cups.
Combined classes for big fields; it's going to sort the men out from the boys!!


Anyway, cheer up fellas. There is plenty to be proud of...

100% Brent. Park them buckets for a week or 2. Come and smash out some laps on the F3 bikes. (or whatever bike you want as look like you can ride anything yah want).
It would be super cool to see you guys out there again. And yes chuck some pics of the GPR goodness in the F3 thread. Its needs some of your input.

[chrisc]

Yeah the forum has been really quiet, which sucks because I spend about a quarter of my working life with it open in the background haha. Obsessed with racing much!

21 Days/3 weeks until the first round of VMCC. I need to get my shit together for the winter series!

Sweet, where do we sign up, and how much cheating can I do on a budget, of well. really - lunch money.

Mmm, lunch.

Man your a hard man to please...
O'well guess you won't be out riding in intermediate class then.

Shame as seeing two of the V4 400s out would be interesting and the restructure was designed for club racing fun..

Knowing Scott very well, it is a good idea to let him have a wee break now to recharge the batteries. Relentless racing must be very hard on his body, more then anyone else.

I have restarted doing some more on that two stroke again, purist bucket racers are a sadist bunch, but better then being accused of chequebook racing...;)

Yea I know. Wasn't really giving him shit, just continuation of the weekends conversation. I know he's getting grumpy about the carb issue on the VFR...


Good to hear your back onto the two stroker project.

purist bucket racers are a sadist bunch,

eh? Man I want to join your team.

[Grumph]

What ? Can't find any FCR downdrafts ? Can't get stock CV's to work ?

[Bert]

What ? Can't find any FCR downdrafts ? Can't get stock CV's to work ?

I think....
Issues with CVs, the good old VFR issue of sitting around for a while and turning to shit...
Not running on all four: but has new plugs, leads... Spark.

FCR down drafts. What a mission to find or replicate (I guessing you have a solution or an idea)...

[Grumph]

Sets of four in line FCR's - 33's for preference - are around. Not that hard to split them into pairs.
Would need a double cable setup or decent splitters.
Back in the early days of F3, I split something like six sets of RS mikunis into pairs for the 500 Kawas, god only knows where they all are now.

The two NC30's which came out of the japanese F3 wars and were ridden here by the Roberts brothers in year 2 and 3 of F3, had CV's I think with HRC jetting kits. I seem to remember seeing open bellmouths in the airbox with no filter.

From experience with the Britten injection manifolding, I can tell you that that lot will be heavier than carbs.
If you want to do it properly, do it like John did and cast them from a carbon fiber based bog.
The final version of the Britten ones were unbelievably light - and they seem to have lasted well too, I've never heard of anyone needing a replacement.

[mr bucketracer]

ohwell dynoed the nc30 engine and 53hp , hoping for 63hp out the standard engine

It's all about compression on those things. i was shown a set of 400cc pistons a guy down here did on cnc some years ago. I said very nice but why are you wasting your time on that pos...didn't go down well. On those you can't machine anything to get more com due to the cam setup. On the RC30 you could shim the cam towers up to compensate for what came off the heads not on the NC.
Have you done the crank clearances ? as they come they're way too tight. Going to the thinnest shells - yellow ? - is worth about 5 HP. Same shells as the VF400F

[seymour14]

Cool sidecar videos, seymour, thanks for posting. Lets hope we have more next year. Chris

Cheers mate, I think those numbers and enthusiasm is building nicely in the background.

I may have swung too much in the GP though, have just got back from Hospital having had appendicitis, the Doctors cut it out last night. Did a good job though, as I am on my feet and out of there having had the 3 1/2 hour operation finish at 11pm last night. Keyhole surgery is the business!

Sorry ChrisC, the you know what parts are still to be done, and I have been told to stay away from work for a day or three. That comment will stir interest up in the natives...:msn-wink:

Beauty of the current F3 rules is you can take them to 450 so the comp is a two birds one stone.
The pistons and blanks are available from the UK

Shit Kerry that's a committed way to improve the power to weight ratio!

Good to hear it went well.

Yerss...tell that to the owner of the blown 450 Kawasaki sitting on my bench. I didn't build it but it looks like i'm rebuilding it after a rod broke.
from memory, i'd say the kawa rods are beefier than the NC30. And the oiling is better on the kawasaki cranks too.

Pics and I'll give a comparison Wgtn DHB to Canty DHB food....Have your sins caught up to you ?

The Kawa motor has the earlier rods I believe. Quote from Andy Bolwell - who also didn't build this one - "it's cheaper to buy another motor than buy a set of the late rods" Hmmm.
To relieve your mind, it's a south island build.

Ops thought about what you were talking about.... Your ZXRs... My bad.
Maybe you should put them back together and hire them out...

Progress is being made, CNC history making, scratch that, CNC Head making!

Mostly milled till I got to the angled fins, then I just cut them out on the bandsaw for that classic GPR homebuilt look...

Tallest vertical fins are 73mm high and 2.5mm wide at the top. Suck on that you CNC amateurs. :msn-wink:

I realise I'm a bit late to the party but here's the RSA combustion chamber design for your mark II head

[seymour14]

That's far too complicated for me, I will just wing it...:blink:

Have made inserts for the exhaust stub that can be removed, so have the ability to change the flow from mild to radical at will. Will test with some of our trick exhausts from years gone by, and I guess we will see what can be extracted out of this little beastie. Won't show you the inserts (patents pending LOL), but the oval shape on the exhaust stub can be changed and blended with simple inserts. Heat removal is Regan's little puppy, he has a radical new design departure up his sleeve to try.

Yeah, I heard about that you sly bugger, but worth a try nonetheless. So they are dumping all that landslide crap into your property, you'd think the least they could do is build a bucket racing track on top of it a little down the track!

Still, will make for a good dirt track, better get some nobblys on the FXR...

[seymour14]

Stacking those pieces together, mmmmmm yummy!!

Barrel and sleeve together, Head needs a spark plug tap put down it and then adjusted for height. Nicosil cost $480 so Regan tells me.

Tomorrow is D-Day for pushing my bottom plate with the curved fingers into place, then it is a matter of giving it to Dad, whereupon he has a precise mandrel to push the whole barrel on and quietly face both ends to get it square and to length. The keen eyed can now look at my exhaust stubs to see what I've been up to, ability to modify as required.

At that point job done, should make it out for the North Island Series and we can see what this puppy has.

Can't wait, some two stroke history in the offing...

[Grumph]

How far does the crack in the top barrel fin extend ?

[seymour14]

The barrel fins were all two pieces. The lowest ones were pushed into place (slightly spigotted into the barrel) and welded front and back, then cleaned up. The next "two piece" fin would then be pushed together and welded and so forth. The crack is just the join mark of the lefthand and righthand part of each fin. They are solid as, so not worried about them.

If there was any worry, it is that the gap between fins may be too narrow, I think the heat dispersal will come from the head though mostly, and the barrel not so much. Testing will prove what needs to happen next.

fair enough. when finished, spray with black etch prime. It will help...

We used to spray paint our rotary moulding castings with black to pull heat into certain areas. Silver was used to draw heat away from other areas.

Not sure about the net effect on a barrel and head, but I will be doing a MadMax4 and spray painting my lips chrome silver so that I can dine with the motorcycling gods if I pull this off... LOL!!

Good old Maori chrome fixes anything!

I think the heat dispersal will come from the head though mostly, and the barrel not so much.
yeah nah. The exhaust gases go out the exhaust port, and when you over rev they'll even go back down the transfer ducts. My cylinder gets stupidly hot, note the hot spot is on the cylinder fins just above the exhaust duct exit

Your cylinder mounting holes are wide spaced, what bottom end is it bolting up to, an RG150?

Stacking those pieces together, mmmmmm yummy!!

Barrel and sleeve together, Head needs a spark plug tap put down it and then adjusted for height. Nicosil cost $480 so Regan tells me.

Tomorrow is D-Day for pushing my bottom plate with the curved fingers into place, then it is a matter of giving it to Dad, whereupon he has a precise mandrel to push the whole barrel on and quietly face both ends to get it square and to length. The keen eyed can now look at my exhaust stubs to see what I've been up to, ability to modify as required.

At that point job done, should make it out for the North Island Series and we can see what this puppy has.

Can't wait, some two stroke history in the offing...

Beautiful work mate. Can't help but notice that sharp edges on the transfer port divider/septum and the sharp edge on the inner cylinder wall.

Although the cylinder septums aren't sharp, rather blocky, the sharp edges do deserve this beautiful wobbly quote

Sharpen the transfer septums and I will personally bend you over and do horrid things with your arse.
Sharp leading edges are used on supersonic aircraft, when your transfer flow goes supersonic then so will the bike.
Look at the fastest two stroke in the worlds septum, does that look sharp???

The final porting will happen in the next few days that will soften the lines and blend it all back to the donor crankcase. Am happy to say that the curved fingers slipped in beautifully with just a heating of the support plate, and freezing the barrel ever so slightly. Once pushed together I have bolted the whole arrangement up tight as it shrunk fit into place. About 2 hundredths interference fit.

Once the barrel is back together (correct the issue that arose at Hawkes Bay north island round a few years back).

Then we can get onto sorting out this issues.
I've learnt a lot playing with the Richards' 300s.
I think some of the drop can be resolved with improved power valve operation.
Lifting the barrel to get a little more than the 122 transfer duration.
Then maybe time to look at the pipe again...

Scotty, do you think it's possible to press the sleeve out completely? To do some work on it?

:gob: Yes, yes, yes. 122 is enduro bike like performance. Have you run the port rubbing through port map analyser? Its a great tool to help match angle areas.

He's saying it opening too soon. But barrel is feckef with crazy low vs crazy high timing,

[Bert]

More detail please Dave?

I didn't think it was completely feckef??

[F5 Dave]

Detail is I'm on holiday and staying up too late drinking grape juice so please excuse the rhetoric.

Memory had your transfers at 122 and your exhaust already at quite a high number. Barrel raise might make that crazy high. Although the PV does help of course.

. But on a race engine PV would be better geared down for less movement but faster perhaps. Random thought.

If your sleeve is out you could preport the transfers a bit and finish transition in barrel. Where are floors at BDC wrt piston?

[Yow Ling]

The power valve spool has to be really close to the piston face to have any effect.having the spool 3mm away from the piston isn't helpful

[Bert]

Valid and that's the theory we were working with.

But.... We were a little shocked when we did comparison fully open and fully closed.

Gut feel was that when closed it disrupts the gas flow out of the port (rather than stop it completely). Same for the returning wave at the small cost to the piston face (but never had a issue) - but it never did more than 25-30 hrs in total.

Ideally, the cylinder would be offset bored closer to the power valve. But I guess that would have created other issues...

The 125 project will be streets ahead of any 110 as it's got 30yrs more modern technology in the porting. If its done right it'll be the biz. Suppose you start with a modern RS125 pipe and go from there. Wob had posted a tweaked design about a year or so back.

I do have one but I am still not convinced esp when you last said MX80's
Imagine how much shit that would cause with the Air Cooled set.
ESP if someone rolled up on a 2015 KTM85


Its not an even year so I'm not going to talk about MX85/MX80...
But yes, shit storm - but there isn't really any AC sidecars out there.

Actually....
Maybe it's odd year I talk about MX85...

Maybe there could be an evolution here:
MX85 pre2010 (standard CDI).
125 air cooled twostroke (carb restriction 28mm)
150cc four valve fourstroke - watercooled
180cc four valve four strokes - air cooled
210cc two valve four strokes - air cooled.


No need for cheap shots, besides I bought it from a catalogue :motu:.

Fuelling the fire....

56mm 125 barrel and have the special crank to show , 108cc

I thought it was a re bore allowance not a de stroke allowance.

But if its allowed I have a good 54mm NSR250 cylinder and with a de stroke of 2mm I could have a 109.9 cc engine with the same bore stroke ratio of my old Suzuki GP.

A de stroke should be easy as we replace the 19mm Suzuki pin with a 22mm Yamaha one. So offsetting it 1mm would not be too hard.

Your idea has got me seriously thinking about abandoning the 125cc RGV air cooled project and using the bits to make a water cooled NSR/GP110 with a plenum and fuel injection.

You have got me thinking now ..... :scratch:

keep the stroke and debore with 52mm strike pistons.
What's the bet Sketchy will be along soon as someone said MX85

It's so loose Rob, yes I believe the intent is rebore: but no closed loop to stop the possibility of interpretation as a maximum CC range.
This is the issue with writing rules, they need to be consistent and limit interpretations.

[mr bucketracer]

tell you what tz , you have given me the idea as i built a tf bottom end - rgv100 top end years ago i think standard there 56mm ? , that new short stroke crank makes it 108 cc , just put it in that engine , spiget head into barral , richerd got my sp rgv250 heads bugger it but may not have to port it ..314351

Clever work on the crank.

Do you still have the other parts for the TF/RGV100 engine?

15s from memory.
Cylinder covered in piston... Not sure if the coating is toast...
Forgot about the piston... That's where they came from.

This is what I had, around 1992-3. Got pictures of the engine somewhere but a search of threads didn't find them. Ran it at Masterton with a stock size cylinder but had cooling probs due to inadequate waterpump

Been chatting to TZ about a TS/RGV hybrid and finally found a few shots of an older effort. Shame I didn't know a bit more about tuning back then.

Not so much the size just its silly unable to get much in the way of decent bearing size.

[mr bucketracer]

Not so much the size just its silly unable to get much in the way of decent bearing size.useing the standard rod , think the rm125 rod are the same part number ? or am i just breathing steam , think the main brearing had the promblem as i recall

[husaberg]

useing the standard rod , think the rm125 rod are the same part number ? or am i just breathing steam , think the main brearing had the promblem as i recall

If you made it 20 or 22 there would be more scope. Plus were you not destroking it anyway? Two birds one stone.

[speedpro]

useing the standard rod , think the rm125 rod are the same part number ? or am i just breathing steam , think the main brearing had the promblem as i recall

As I recall the rods all got superseded to the RM rod.

[husaberg]

As I recall the rods all got superseded to the RM rod.

The early Cr80 bearing is the same part number now for the Honda Lead125. I think it might be the same for the MB50 too.
I just thought going to 20mm or 22mm would open it up for better aftermarket stuff.

A most successful day for the GPR sidecar satellite team...
Fabrication done by a new team member Dale - while I cracked open beers and talked shit.
Same time we built a basic jig so if it works ok then more can be made easily enough.
A little bit of recycling - my old FXR frame donated its headset.

Shinny and bits of bling.

They might still have a few left.
Then again you could diy a set out of pitbike stuff now as they have the 13mm pins.

I'm almost finished one...454cc, web cam & springs (when the dollar was good...) 24mm carbs, Dyna.
CB250RS wheels, Z disc with Z1 caliper. FOUR pipes...hydroformed curved meggas.
plenty of piston kits on ebay still. No one wants them as every bugger wants original 400 parts.

Let me know by PM if you want to know how to increase the oil pump capacity, not hard, easy to find bits....

re the BSA/Triumph threes - Dick Mann reckoned the best noise they made was the moan when they pulled back onto the band after you'd fucked up a corner.
Very, very, forgiving.

I would have only been 10 or so.

The 350/4 was pretty all revs no action, punching the engine out a few mm to 408cc made it a sweet engine.

Yes the one in the video is just idling around really. I remember chasing one with my TZ and up close peeling into then powering out of the turns I could feel the exhaust pulses banging against my helmet and chest. Close enough to see right inside the megaphone, 3 into 1 and open mega, what a sound, thought I was in heaven. The sound and the thumping from the exhaust, that was truly something. Then there was the high pipe Norton Commando. I was moving in to lean on it as we entered a turn and as he throttled of it backfired. My ear must have been level with the exhaust, the pain was overwhelming and I have been deaf on that side more or less ever since. Ahhh those big British race bikes, love em.

Ther was a period where that sounded OK where he was near a TZ but the rest sounded tedious. Coming from the owner of a Triumph triple.
NSR500V like two CR250s side by side. But the 4s are even better.

Not sure that's worse than when I backed off my bsa in front of Owen Galbraith at Ruapuna - high pipe right in his face. Open face helmet too...he reckoned he got a dose of castor oil in the face, some of which he swallowed....

A guy down here built one of those Honda 4 replicas using a late water cooled motor. It was the early days of CAMS and he wanted to parade it at a Rakaia street race meeting. The then powers within the club wouldn't let him....pretty sure it would be viewed differently now, at least for a parade.

Good to hear it is running again, that thing looked to have huge potential. Do I need to come up and celebrate with you?

Speaking of which, how is young bro going on that two stroke project, have I made everything too tight to fit properly?
