Been busy doing some engineering this week. Fitting the forks is a breeze as they fit in the rs triple clamps, however the rest is not so easy. There is an option on the forks of 4 pot or 6 pot calliper, well it would be rude not to i thought. not sure if the 4 pot would have been simpler but its not been easy. The GSXR wheel almost certainly wouldn't fit as the RS tyre doesn't have more than about 5mm clearance each side. The calliper fitted with the wheel centralised clangs on the wheel webs. 
I took the calliper apart and removed a piston on the back half and measured the casting thickness at 6mm so i machined 2mm off the back of that, took a few mm off the back of the calliper mounts and likewise on the fork mounts, its nearly there, i'll get some small spacers maybe 4mm to space off the disc and we should be about there.
The axle is another story. GSXR axle is 25mm RS is 20mm. You can't get bearings with 25mm id to fit in the RS wheel so it needs a special axle, which can be made using both axles and a lathe. Had to make the spacer/sleeve shown in photo 2 on my little lathe and it took most of the day today. Its an old Myford ML2 belt drive. and its slow work.  
I would like to remove the calliper bracket from the LH leg but i am going to wait and see whats what with the mudguard first.
Got some useful info on the oil system from a chap in holland. Its a pressurised system so i can't use the plastic tank i had in mind. Now going to use an oil cooler. The microgilter used on the bikes that didn't have oil in frame only held .5 litre so i think the Triumph cooler i have should be ok.

Engine Vibrations

Well after riding Stuarts 640 supermoto and this bike back to back, the vibration had to be coming from somewhere. The rear mount was one thing I hadn't paid too uch attention to when I started the project. Stripped it down at the weekend. I dropped the back of the engine and managed to drift one of the top hat spacers out, but the other one wasn't  having it. Decided to take engine right out to get better access. Was thinking I might have to drill it out. Made a drift from a long stainless bolt and machined the head in the lathe making the lip thinner eventually, with the lip about .5mm thick I got a good contact with the end of the bush and got the bugger out. Both the spacers were about 1mm oversize on the ID so the back of the engine had about 1mm of play.  Next job is to make some new spacers and fit them, have ordered some bar stock for that. May move the oil cooler while its apart.
Been working on cooling system now exhaust is done. Bought TDM850 Rad which has a pressure cap thinking i wouldn't need a separate expansion tank. Now the rad is mounted as high as i can get it, the filler is not the highest point on the system so will need a small expansion tank to fill from. Ordered a RS125 one that should do the job. Fitted some hoses but need some more bends to plumb the red in neatly. Its very congested and tricky round the water pump area.
