My new Project.. From Chop to...
Discussion
After all the hassle with getting the rear wheel airtight, we didn't take any chances with the front wheel. We machined a bevel in the top edge of the wheel centre where it joins with the rims to make it easier to apply the sealant. While the rim edges were checked and double checked for any burrs etc before we bolted them to the centre using plenty of good quality gasket sealant.
The Suzuki GSXR 750 K8 disc I was given needed an adaptor making to mount it to the hub, its not very pretty but it will do for now, it can be drilled / lightened / shaped later. The disc bolts aren't anything special (far too expensive), they're just standard hex head bolts which have been 'tickled' in the lathe.
I'll wait a few days for the sealant to fully cure before getting a tyre fitted and polishing the rims.

Still waiting for the coil and tacho to arrive, till then don't want to start making the wiring harness. I really want to get the bike running and on the dyno before mid December, so I've been scratching around for the final bits to get it running asap. For example, I didn't have the correct size HD throttle cable, so I modified an old cable I was given to work with the Mikuni carb, it works fine, pity about the colour, beggars cant be choosers
The front wheel turned out to be airtight thankfully, with a used (free) tyre the bike was finally on its wheels, so I could push it outside and make brmmmm brummmm noises when nobody was looking. But not before I had the local machine shop extend the M18 thread a few mm to match the slightly wider than standard yokes. This didn't come cheap.. cost me a box of Mr Kiplings finest Mince pies...
Also made a simple hand change and finally got the clutch adjustment right.
Picked up a tired ZZR1100 caliper which fits the ZXR750 forks on the bike. I've ordered new seals for it, and a trip to a bead blaster would clean up the grotty body.. think I'll need to buy another box of Mince pies
Also made a simple hand change and finally got the clutch adjustment right.

Very cool...

Im liing that as a roadbike tbh....
The gear change would be tricky with the rearsets, though not impossible, as I had rear sets on my last Evo drag bike. As for it being a road bike, I have a Evo big twin already with a 131 Cubic inch engine. They aren't easy to live with, one is enough for me.Done a few small jobs over xmas, the frame down tubes are thicker than those on a standard HD, so we made a couple of frame clamps to hold the clutch cable in place. The second job was to machine out the centre of the clutch/pulley cover. This exposes the clutch, so the pressure plate and push rod adjuster nuts can be accessed quickly without having to unbolt the cover each time.
Almost ready to put the bike on the dyno, though hit an unexpected problem with the starter pinion... in that there isn't one. Its a non standard part which comes with the belt primary kit, but its missing. Its either been lost or someone 'borrowed' it without asking me some time ago, will have to order a spare from the states, in the meantime its possible that the bike could be started via the dyno drum, not sure if its powerful enough.
I fitted a Tacho with a built in shift light, ideally I'd want one which red lined at 5 or 7k, but this one will do, and I'm tempted to program it to read double since max power will be made at not much more than 5k.
Made up the ignition leads which turned out to be a right pita, and sorted out the front brake spacers too.

On a different note, my mate Jeff won a bid on a few parts on Ebay last week, by one of those flukes, turns out the seller owns the first drag bike Jeff built back in the eighties, the bike that Jeff was slowly acquiring parts to replicate one day. Its been changed a bit over the years, it now has a 250cc engine, a Wade supercharger (when the original exploded!), an air shifter, hydraulic clutch and a different tank and seat etc. The home made frame and handmade yokes (the first he ever made) are still the same as is the front end. Well, turns out the chaps wife was nagging him to get rid of some of his old junk (he still has a supercharged BSA) so Jeff bought it along with a pile of spares. Including a half completed engine, which Jeff had started to build when he sold the bike more than twenty years ago. This spare 350cc engine has a much stronger home made three speed box, built by Jeff using CB750 parts, as running it on Nitro used to break the standard box regularly.
I'll no doubt be roped in to help out here and there, be interesting to see how it turns out.

Back to my bike, which I've not had much time to work on recently, so I'm behind where I'd planned to be with it, not that it really matters, I'll still get to race it this summer (fingers crossed)..
The fork brace made for the 43mm forks was originally meant for yokes which were 4mm wider, I thought that I'd have to make a new centre section. But with some machining and 'stretching' the mounting holes by a couple of mm each side it was made to fit.
