road bike project scratch built

[Ian Staples]

Hi guys . for my own amusement I am building a road bike from scratch. It is basicly a "80s" superbike /kit bike tribute using a cb900 engine and gsxr roling gear the rest is just a matter of bending some bits of metal and welding them together . I do have one question someone may be able to help with. When you use late model wheels what do people do for a speedo as I would like to use original cb instruments but of course the front wheel has no cable drive. Also I am after a CB1100f clutch cover as I have gone and put a frame tube in the road of the 900 clutch actuator lever and the easiest way around it is to use the 1100 cover as it has the lever coming out the front of the case instead of the 750/900 rear

Could you run a 90 degree reduction drive off the front sprocket cover for the speedo, something like a Brit bike tacho drive?
Put up some pics of the build. I'd bet it's art after seeing your sidecar up close.

[jellywrestler]

motogadget do electronic speedos, to keep the instrument look you may be able to fit a speedo into the existing case and use the original face plate. check out the part numbers for the cb900f and cb1100f gaskets to see whether they are both the same as it wold be a shame to find out if the covers are different and they've changed the cases along the way, japs are funny when it comes to this

[pete376403]

I have seen (somewhere on the web) conventional looking instruments that have electronic mechs ( ie a stepper motor to move the needle) so do not require a mechanical drive

Yes, you can. Honda NC30 and I think CBR400 run this setup. The bits should be available in NZ - unlike CB1100F clutch covers. While there are a number of CB1100R's in NZ, I don't think any of the cooking F's were imported. Spyda's link to ebay is probably your best bet there - if it fits. The 900 cranks will drop into the 1100 - but I don't know about the cases and covers.
Vince Sharpe and his mate in Auckland do a better tensioner setup for the camchain on those engines. I've fitted one on a road motor for a customer. Well worth doing IMO.

the 1100F's were imported but there weren't a lot sold, clutch cover for the 900 and 1100 have the same part number so . i wonder how symetricla the cover is part way up and whether if desparate that the top could be sliced off and rotated and glued back on?

Looking at the pics Husa has posted elsewhere, I'd think that's do-able. To add to what I posted before, now you've confirmed the 1100F came in, ask Vince Sharpe if he's got any bits. That group seem to have got down on any loose CB900 parts so may have 1100 parts too.

its a part xr69/ McIntosh/bimota/harris/whatever is in my head. I will put up a photo later on. I can cut and shut the 900 clutch lever and make it work but the best option is the 1100f . I checked out the gasket and they are the same for 1100 and 900 but as you guys have pointed out 1100f parts are hard to come by . not sure why honda moved the lever to the front of the case on the 1100 . another option I have is to convert it to hydraulic but I am trying to keep it early "80s" period-ish and I'm not sure if hydraulics were a thing back then. the other option for instruments is to use a separate electronic tach like the early gsxr750 and get a small electronic speedo and make up a dash . this option I quite like as it would be a bit more racer than road bike.

Have a look at R1/R6 or Aprilia RS125 or Sv650 or GSXR
There is plenty of stuff on the net about rejigging R1/R6

When he said GSXR running gear oi was thinking the oil colled stuff

so what's stopping you turning the clutch arm 90 degrees and re routing the clutch cable behind the motor and up then?

[Grumph]

Very nice so far. Yes, lots of Moto Martin influence visible, nothing wrong with that.
Over the years I've built I think, only two frames where the engine has to be dropped to do valve clearances. In my experience it invariably leads to a lot of very bad language and frustration. I wouldn't have recommended doing it.
Still sorting the swingarm and jig ?

A better pic of the area behind the clutch cover would certainly help the hive mind to come up with any ideas...

i couldn't be arsesed going to the bookshelf and scanning so i googled the one i was thinking of

900fz were around in 1979, if it's to be done this way you'll need proof that it was on the road in a similar modified state back then, otherwise it will need low volume cert, going through the process soon with this, have magazine articles from the day so that will help

I would have thought it would make the process a lot easier by using the original headstock and or frame tube that held the frame number?
Then getting the mods certified, You used to be able to? the big iie was the powers that be used the frame to determine the basis.
I can remember getting a bike registered with no ownership papers it used to require a letter from a JP. Something from the police as well. It was complicated back then.
Do these new rules apply to cars as well?

first two pics it looks like it has an outside arm pivoted in the middle unless its the fin on the cover?
But the other pics suggest a pusher from the other side which looking at some blury pics looks to be hydraulic (middle last pic)

i might need to look at a CBX750 but pretty sure they were hydraulic clutch as was the first VT250 so its period aceptable

Here we go CBX750

low certification is not a hard process if the job is done well, the guys who are qualified to do it are clever cunts and able to sort out what will work and not, biggest issue is travelling to them as car certifiers and bike certifiers are different, not sure where the closest bike certifier is to wanganui. using the original headstock would unlikely work as i'd lay money that a gsxr of what's used here and a cb900 from the 70's or eighties is a little different in dimensions. the aim here would be for it to be 'registered' as the motor year build rather than 2019 as rego is a fraction of the cost. the other thing is to consider is the looming ABS implications as i'd mentioned earlier, but I don't know the process there, someone said november so maybe if the build is certified before then it wouldn't be a problem.....
one of the hardest things i've found is the indicators, they must have a system that if one bulb fails that side flashes twice as fast as normal, with leds and modern flashers that's hard, i used motogadget in mine custom and despite being a top line product it didn't do that. again, i don't have to get low a low volume cert for that, and maybe the low volume certifier will turn a blind eye to that but one wouldn't want to get there and find out different.

[Grumph]

To go back to the original problem of the clutch arm...Without changing gearboxes etc.

Two solutions come to mind - even without better pics.

I'd think that moving the outer lever arm on the shaft so as to aim the cable inboard and up might work.

The other option could be to reverse the internal cam on the clutch actuating shaft so that the cable pulls downwards - where there is room to work.

See I was thinking there's a heap of great twist & go engines out there that would do away with the need for a manual clutch altogether.

He's talking CVT big scooters. I don't think they're at the point yet where you could use one as a base for a sportbike.
Though I believe Gilera did one around 800cc.
There's no real equivalent yet to the Porsche Tiptronic AFAIK.

we all have X amount of senses, on a bike there are few used that are unique to a bvike ride, the rest is emotions, sound is the most important and the only one fully triggered by riding, electric bikes throw that out of the window.... additioanlly, moving through the gears is part of the ride, take that away and no thanks.

Damo Rees was raving about the Honda DCT system to me a few weeks back, not quite ready to race yet, but better that manual by a fair stretch.
I'm going to take his word for it, I know how he rides.

[Ian Staples]

Hi Guys . thanks for your input . My first idea for the clutch lever problem was to rotate it 90 degrees so its points down and run the cable horizontally along the back of the engine. and this should work ok but the cable will run a fairly torturous path. Then I spied the 1100f cover so that would be the most preferred option , although I could still possibly convert it to hydraulic.

as far as certifying for road use goes .I emailed the low volume people and asked for a list of requirements for motorcycles and bizarrely was told apart from the WOF regs there weren't any only to follow what's in the car manual and I was best to talk to a certifier. I found a certifier close by an had a good chat with him and he sounded really good . The bottom line was if you turn up with a well built motor cycle that looks like a motorcycle ie nothing like a alloy monoquoque (that had the spell check stuffed ! ) oh and don't weld castings and if it complies with all of the WOF rules there should be no problem getting it past. so my plan is to rock up with a finished bike and hope like hell he likes it . beside from some of the choppers I have seen. It cant be to hard to get a low volume cert as all you need is a length of steam pipe and a spider web gusset here and then and a skull or two for good measure !!
Of course If they change the law making abs compulsory then I am doomed. then the bike will probably end up in the corner of my shed with a cover over it or in a car/bike museum.

The swing arm is next on the list and I am just trying to find the steel box section I want without buying a 5.5mtr length. I am trying to build this on the cheap and so far have succeeded. but it might slow down or come to a grinding halt when I need to speed real money on it. I don't have an engine yet and there are only borrowed cases so if anyone knows of one laying around please let me know also after cb switch blocks and loom etc

Originally I had wanted to put late model rolling gear on a CB ( yes the old nostalgia thing kicks ia as I had a 750 when I was 18) but when I started looking on line and while they are very cool it all been done before a million times and it wasn't really enough of a project for me . I am more interested in the project rather than having a road bike as such which is why I am not worried about having to remove the engine to do the tappets etc if the bike does 5000ks in its life I would be surprised. at this stage I don't even know if I can even get the motor out of the frame as it is very tight in there .I would be very pleasantly surprised if I can but my plan if I can't is to cut the front down tubes and make them removable if it doesn't . I should find out this week .

Regards Ian Staples

I probably will go for a electronic tacho like the early gsxr or something that looks ok out in the open so then will need a small diameter speedo that I can make work then make a binical with some small idiot lights in it ,like I said more racer than road.

[Grumph]

Totally agree re the certifying of choppers, lol. What section/thickness are you looking for re the arm ?

I said earlier Vince Sharpe for a cover etc - try him for a motor too.

[jellywrestler]

.

it's changing, to what extent i don't know re low volume, ask your certifier, i recall Joe Lett saying november so get it there before if it is the case.

as for complying with WOF rules the warrant of fitness people are there to essentially check that what is there functions, not that it is designed and placed correctly etc, there's a bit more to it than that, there's five pages on indicators alone, just been through the whole build thing within the guidelines, headlight heights and the indicator flashing thing i mentioned, warning lights too were about all i saw as needing attention, they won't check those at a warrant, but a certifier should,.
and make a space for the low volume lable to be riveted on, that's something most people miss along the way then have to weld shit on afterwards.

[F5 Dave]

Hahaha, your comment about engine removal reminded me of my special. Heavily braced RG250 frame with a 500 in it, I designed the rails for weldy guy to electric glue on giving me enough space to get the engine in.

He had a better idea of where the rail should really go.

Engine didn't fit.

So over several beers I took off the head (2 stroke twin), side cover and even the sump bolt. With a special rotating twist I can just get it in. But I have to get drunk to remember how to do it. So it's not all bad:drinkup:

Just a male and female taper through bolted. My emco lathe has the same to mount the chuck - just a bigger PCD.
As a frame joint, I'd call it a tad over-engineered.

it would take longer to do a U turn on an SB2 than it did to take the bike apart to do the tappets nearly, steering lock was about the worst on any motorcycle. they learnt and my SB3 has a chunk out of the frame to let the forks turn a bit more....

:first:Such details are all part of the Italian experience.
if functionality was the main concern you would have bought a Honda
Other than a Manta or a bb Single i don't think i have seen a Bimota i haven't lusted after.
I used to think the SB2 and 3 were ugly but i really like them now.

Rod Coleman had always wanted an Italian bike but new they were finicky fuckers, when he was in the states he saw the SB3 I own and grabbed it to tick that one off his list, it's a magic thing to ride too

Hi Guys . I am going to build a steel triangulated swing arm But the problem I have is I can't get the rectangular erw I want . I can get 51x32 x2 Which may look a but small or 62 x35x2 ( I have a short piece of ) but it looks a bit chunky, It would probably be ok if it wasn't triangulated The size I really want is 57x35 but they don't make it any more. Looking at photos of 80s kit bikes I would probably lean towards the 51x35. Also not sure weather to use round or box for the triangulation.
Got the motor out but had to cut one front down tube as expected

rear suspension is a copy of the xr69 Suzuki. The bimota had quit a small box section for it's swing arm and no triangulation and its very long. from memory in the day some thought that was a problem.
I always loved the bimotas and had a magazine I kept for years with the KB2 which I thought was the most beautiful piece of engineering.

Regards Ian

Only my opinion - but I think you're going too big if you're triangulating it as well. I'd use 2X1 - ie 52X25 - and 1.8mm wall too. I've made a few arms from this and they finish up very stiff. Foale somewhere goes through the calculations - lateral vs vertical loads - and finished up with 2X1 16G...
Any wider section horizontally and you're starting to get tight for room at the pivot end - particularly if you're using a wide tyre.
I'd use round for the triangulation - it bends easier.
Alloy blocks in the ends of course for axle location. You'll be surprised how stiff it finishes up.
2X1 is pretty common. I've got probably half a stick left here.

If thats the case Ian surely seeing as you used modern forks and wheels why not just use the Srad swingarm as its a beefier version of a similar look? or Triarm? or FZR/YZF
Or is it just about building it yourself as you clearly have the fab skills?

I had a bit of a win on ebay. I found a 1100f clutch cover in france for 30 euro but they wanted 202 euro shipping . I asked them to look at postage and they come back with 25 euro so for a total of $97 nzd I have the clutch lever problem solved !!

Hey Ian could you put up a few detail pics of your sidecar on here please, with back story's on how you created various bits & pieces.
I read your build in NZSRA newsletter, I think members on here would find it very interesting.
Thanks, Steve.

[jellywrestler]

had a good chat with an LVV m/c certifier today, he only does half of it, he does the structural certifying then it goes to the people who vin it to check the placement of shit. interestingly if it fails, you have 21 days to get it back otherwise it's start again and pay full price, that will be a pain especially if there's no-one locally.......

As some one suggested previously ABS will be compulsory for new bikes april 2020 so my project may be dead in the water as I have little chance getting it on the road by then . I see they will be some exemptions for classics and collectable and I have just emailed nzta to ask for the criteria but I would suspect with this idiotic government and the car /motorcycle hater Julieanne Genter at the helm of this that the would not have thought this far enough through. I am currently working on the swing arm so I should have it on the ground rolling and intend to take it to the certifier and see what he has to say.

why is abs a bad idea, it's not expensive when it's legislated in compared to not, it's a safety tool that a large percentage of riders would benefit from....

except to check the speedo functions why does a bike have to actually be running to get certified?

[Ian Staples]

I am not saying abs is bad at all I think it is a very good thing but I doubt you could buy a retro fit system for a one off build

What about a full system off a donor bike? They're essentially a stand alone system.
I have a complete system off an R3, weighs about 3kg if you wanted to try something.
It's missing the front ring from memory.

[Ian Staples]

Hi All. I have made some progress. got the swingarm almost finished and the bike on its wheels. It's always good to see something on the ground where it is supposed to be so you can see if it looks right as being up on a stand can skew things a bit. I am pretty happy with the way it looks. I took it to the certifier today and we had a good chat. he couldn't see to much wrong and filled me in on the procedure. He is sure that the ABS ( thanks bob re the ABS) thing won't be a problem under the LVV system but I am not so convinced. I am still waiting to here back from LTNZ. So far they told me there will be 100 exemptions per year for classic and collectables but in the info they sent me it only mentions "Imported " . No mention of LVV bikes . I do suspect that they hadn't thought about them.

[F5 Dave]

Impressive.
Rear shock vertical to almost rearward stance, possibly illusion. Did you base that linkage and placement on something?

[Ian Staples]

The rear suspension concept is a copy of Suzuki XR69 with the ratios set up to give probably longer travel than the XR, the same as the gsxr road bike donor

Hi all
.fully finished the exhaust today. Not sure if I like it or not maybe a 4 into 1 may have looked better but I could always make another one later on.Anyone out there have a side stand surplus ?Some bikes like the gsxr have a bolt on unit and I may be able to adapt it to fit . regards Ian

[Ian Staples]

Hi All. finally got back to working on the bike after quite a few months doing other stuff. This is the outer skin of the fuel tank and for my first ever attempt at alloy work I am rather pleased . It is made up of 5 pieces and much to my surprise I only needed one attempt at each bit. I am still a bit nervous as there are still many opportunities to mess it up before it is finished, as it sits it still needs to have about 50mm cut of the bottom Regards Ian

what's the best engine paint?? I now have a complete cb900 doner bike which has been sitting outside with a railway tarp over it for the last 10 years so it looks terrible . It wont be for a while yet but I will bead blast the engine and paint it so the big question is what paint to use ???

Hi Laava, sorry, haven't been on site for a while....
The paint I use is available from Resene Automotive Paints and is called Durapox. It's a 2-pack, (so contains isocyanates), but dries as hard as. The only area I've had an issue is the starter cover beneath the carbs where petrol leaked onto it. It's bubbled, so I need to redo that bit.

i used resene durepox on the warlord, Grumph steered me that way. not cheap though, get the cases vapour blasted, bead blasting is for de rusting trailers and garden gates

[Grumph]

Yes and no. There's a guy here in ChCh who I used to use a lot for bead blasting who 1/ only uses the bead once, and 2/ has a dehumidifier in the air supply. Using the fine bead his work was almost up to vaporblasting.

For alloy - like engine cases - yes, vaporblasting every time now. How much of the difference is due to the very fine bead used, I don't know.

For steel pieces - incl frames - that are going to be nickel plated, fine dry bead gives the best surface for plating. If it's not going to be polished prior to plating.

For steel pieces that are going to be painted or powdercoated, grit blasting is the best. Usually garnet grit I believe.

Trailers and garden gates - there are still sandblasters out there living off that stuff.

It's a case of picking the correct options for the job.

[Ian Staples]

The gsx done using the duropox looks fantastic . As far as bead blasting goes I use two beads in my cabinet, garnet for steal and any some alloy, but for the nice alloy I use a white glass bead that feels about the same as caster sugar. The finish looks about the same as vapour blasting and the beauty of it is you can rub you dirty fingers on it and it wont mark. I may do the engine complete so it would be to big for my cabinet so I shall look at getting it vapour blasted . I have leant that it is very hard to mask something like a crankcase to keep all of the beads out

[Grumph]

I'd go so far as to say it's impossible to keep abrasive out of an assembled engine when vaporblasted. It gets past seals quite easily.

Pre lockdown I had this conversation with Kiwimacchi who has a very nice vaporblasting setup. He's extremely reluctant to do complete engines.

Look at it as an opportunity to check the condition of the internals of your Honda. The camchains will need replacement anyway - they all do.
You may even decide to install one of Sharpie's manual camchain tensioners - which I highly recommend.
Gasket sets are readily availale still.

[jellywrestler]

It's a case of picking the correct options for the job. and finding someone who is not an animal

[pete376403]

Unless I am mistaken vapour blasting is more or less wet sandblasting (or bead blasting or whatever-the-media-is blasting) so if the item can't be dry blasted, then it probably can't be wet blasted.
The cheap-ass "vapour blasting" attachment for my Karcher water blaster works really well and makes a nice finish on engine castings but the media (in my case river sand) does get everywhere and past everything

Hi All .

Hi . I looked at that and the problem is the older bikes run small diameter axles and the later much larger so if I bored out the the centre of the 900 drive to take the big axle the would be no gear left unfortunately. The price on the converters mention are about $350usd so that rules that out

I looked at the gsxr 600 wheel bearing size and it would appear to be the same as a 1200 bandit amongst others ,I couldn't find rf900 bearings . I have asked a guy on TM to measure the bore and width of a bandit drive. The other problem is there is quite a small gap between the wheel and fork on the 600. I would be very happy if I could get a cable drive to work

[F5 Dave]

On my RZ I used an R1 dash, then mounted a hall effect sensor (R1 part that usually counts teeth in gearbox) and mounted it on a bracket nderneath the cover counting front sprocket teeth. Then a 12o'clock labs speedo adjuster to calibrate. Took sense from ignition for tachometer. Depends if that's a look you want.

True, but in this case both the bearing are the same, the pictures show the shoulder or no shoulder and in this case the axles are stepped but only to the forks..the pics in the parts fiches also show what side the speedo drive is on in this case its the narrow dia end

Also the listing for the axles spec i put above show left and right dia.

Lots of Hondas were stepped. Surprising they never invented axle sizes for them like the steering head bearings.
Some KTM run bearing sleeves inside the bearings from the spacers

I f he has a drive with the correct diameter I shall take the front end down to him and have a match up session

Its got a 4 piston brembo caliper and a 320mm disk as welll ,same set up as a 1990's 750ss Ducati
i are guessing Bobs one later one post 2002 As it changed that year, had a wider one which i think is the radial brakes one of the last ones has a the digital dash .(i have a dash, it looks like an R1. i posted it on pg 1 )
i would say its fashion and fucntion for the axel. the brakes are likely overkill on the road with 30HP.
the axle size is likely because they figured out a bigger diameter axle that's hollow is lighter and stronger than a thin solid one.
or thats what suited the forks.

Thank you very much husaburg. I did not know that sprocket driven speedos where a factory thing , I have tracked one off a cbr 400 here in Wanganui It should be no bother to mount it for me . this means I can get on with mounting the instruments and sorting a headlight

I knew a few hondas had it, but not this many
Honda Hornet 250 CBR250 MC22
NSR250 MC21 MC28
CBR400 NC23 MC29 CB-1
VFR400 NC30 NC35

Glad it all worked out. Keep up the good work. The bike is great.
edit
Grumph said this first page lol


Yes, you can. Honda NC30 and I think CBR400 run this setup. The bits should be available in NZ - unlike CB1100F clutch covers. While there are a number of CB1100R's in NZ, I don't think any of the cooking F's were imported. Spyda's link to ebay is probably your best bet there - if it fits. The 900 cranks will drop into the 1100 - but I don't know about the cases and covers.
Vince Sharpe and his mate in Auckland do a better tensioner setup for the camchain on those engines. I've fitted one on a road motor for a customer. Well worth doing IMO.

I made my own bracket for a couple magnets that go on the front sprocket.
It's pretty easy to go digital.

easy at that end harder at the dash

I saw some retro looking clocks on Ebay.

[jellywrestler]

I saw some retro looking clocks on Ebay.

he wants to use a cb900f dash to go with the donkey he's running, hence the questions to get the speedo in the original dash running, either cable operating option, or inserting a digital speedo into the existing dash Drew.

[Drew]

or inserting a digital speedo into the existing dash Drew.

That's what I was getting at.

[jellywrestler]

That's what I was getting at.

so it would need to be able to fit in behind what is there so the clocks still look the same and the ratio is still the same too

[Ian Staples]

at this stage I am going with the cb750fa dash and a honda 400 speedo drive of the front sprocket . Hopefully the ratio may be close. My next trick is to find a 6inch headlight, I think the cb 7inch will look a bit big

Fa dash is the same as the dohc k series dash iirc.

[Ian Staples]

I missed that ratio chart the first time but good info thanks. interesting that some Hondas of the era had 7"1 even those wheel driven . I think the sprocket drive (7:1) is the best for packaging and If I need to get the ratio correct in the future.(as long as I get a cert/wof it may not worry me) I may be able to transplant a 7;1 speedo in to the 750fa(4;1) dash

[Bonez]

Ian I've got a CB900 Top gasket set if you want it. Can pick it up if you are over this way or I could drop it off this weekend if it suits. Just PM me your address details and suitable time.

CB750/900/1100 ratio is 4:1 btw.

personally i would just redo the instrument display sticker .
you can actually leave the drive as is and make a sticker. Or as you say just use a drive of that ratio as they are fairly generic i have done that with tachos before MB5 tacho in XL100s housing.
the VF etc had tachos with different electrical configs you can alter built in.

Another thing is the cbr ratio might be 7:1 but its before an approx 3:1 rato secondary drive for the chain :)
so it might disply the same as at 4:1 ratio wheel driven speedo anyway

[Drew]

so it would need to be able to fit in behind what is there so the clocks still look the same and the ratio is still the same too

The ratio on the digital ones is set by wheel circumference.
So do the maths on the sprocket ratio. Then use that division factor on the wheel circumference and enter it.
Accurate to the mm speed reading.

the whole point of using a dash to match the bike is to look the part. I think the aim is to reatin the look and fit shit in behind it to make it work, and look the same, at least that's the way i'd be heading and read it

As long as the thread is currently about speedos, anyone know of a speedo cable outer about 1.0 - 1.1 metres long and which would fit Suzuki speedo drive and speedo (specifically 1982 GS models)? The current cable is 950mm and needs a little extra length to clear the different calipers now installed.

I used CBR600 calipers on my 11 with std mc, just adapter plates. These days would need an LVV cert, and fair enough having seen the Bush adapters I've seen on Buckets.

Geez was 420% better than std. Made some braided lines up. Too long ago to remember how. Maybe I tried the originals and told them 1" longer. Likely Contour brakes.

I've used Alert in Auckland but they were bought out by some rally chap who used his name. Had limited success with them.

MetalGear CBR600 rotors, Concours Mk II calipers (twin spot, big'n'little), Concours master cylinder (span adjustable), FrenTubo braided lines, adapter plates. See how it goes at WoF time wrt to the LVV cert.

[Ian Staples]

Hi All . I talked to the resene man about duropox and he told me it is a primer and not a top coat. He says I need an etch primer underneath . Does this sound correct. He also said he can't sell it to me as they don't sell it to the public so I will have to go through a local painter

Yeah I thought about it and decided to go the LVV cert route. The welding on the brackets has been tested and approved and I have the certificate. I'll go over to Carterton to see Julian Cheer as he is the only semi-local 2B certifier.

(Bonez - for your benefit - the difference between the standard Suzuki brakes and what I now have is so obvious that even a brain-dead tester at VTNZ would realise it is modified)

i brought some walkin from resene in lower hutt, gave it all to my painter near levin as it has a shelf life and better he used it than it sat on mine for a while.
he sorted the primer, and i used it to finish the engine cases barreels and heads on the steve roberts chopper.

[pete376403]

I didn't know he was there, the web shows him in Carterton. Behind Mac would be great, thats just up the road from me

[F5 Dave]

That was Skiddys posi, has he moved?

Dunno about the duropox stuff, but you certainly have to use an acid primer on the raw material if you want anything to stay on there.

[pete376403]

no, Julian was working out of there too.

Not any more. called in this morning, Skid says Julian cant be bothered coming over every day.

[Ian Staples]

I rang resene Palmerston north . Asked for duropox and etch primer. They said a 1ltr kit of duropox consists of 1lt paint 250ml of hardener and 1ltr reducer and 1ltre of etch and 1ltr of etch hardener $180 but they would not sell it to me . Went and saw a local panel beater and he rang them and they said they only sold the hardener in 1ltr so the duropox ( no etch )would cost $270. Fuck that ! so one person there says a completely different thing to the other guy. I tried to ring them again today to find out what the go was . I could not get through to them so I tried Lower hut, Talked to a top bloke called Don . Ended up getting all I wanted ,the invoice emailed to me and I paid via internet and he was happy to courier which surprised me as its DG no charge for freight !! top man, top service !! $181.88

Nice to see you the other day. Got the RHS lower cowling on the XF650 yesterday. Took 3hrs all as oppose to over a day for the LHS :) 1 can of primer suitable fo ABS plastic from Super cheap Autos $25, 2 cans of light grey colour match acrylic lacquer from Resenes Automotive $82. Just used the sand paper Connie had laying about. I'm very happy with the result considering I've never painted a panel that size before. Couldn't imagine what the job would cost by a professional auto painter.

[Bonez]

Hey Ian I found a Clymer DOHC CB900-1100 workshop manual in reasonable condition for its age. Ex librar. I got it from the annual P.N. Red Cross book sale years ago.

Do you want it? I have no use for it at all.
