A few hours of tinkering and I managed to squeeze on my new 'yoshimura' ...rearsets ah..em..From Thailand. They are actually quite neat, very light, machined well apart from a few burs and heavy handed bearing placement but apart from that they look the part...seem sturdy enough...time will tell. All I had to do for the gearshift side was keep the universal joint from the original arm at the gearshaft end, use about 30mm of threaded 6mm bar which screwed into the Thai linkage to the original. The right hand side foot brake was trickier, I had to nibble a tiny amount away from the aluminium frame bolt holes because the hangers were 70mm apart and the Trx's are 73mm apart....why such an odd number....I also had to open the holes out a little on the hangers for the bolts to go in.The master cyclinder had to go in front of the hanger because of it fouling the frame.
The chain alignment...well I had to send the 110 link chain back to A&R racing as it was too short!...so if you use a 45 renthal thundercat sprocket and a 15 or 16 tooth front you will be .a link out!.....so get a 114 link chain. Alignment I found the rear sprocket is too far left, I tried packing the driver sprocket out but could only go about 7-8mm but it isn't enough!...so the only thought is to machine out where the rear sprocket sits....I looked on the trx forum but that seems to give differing advice...and that's for a yzf 750 rear..they suggest add 1mm washers to the sprocket and 4.1 for the front?..strange....
Really I think the best answer is to take the swingarm out and machine off some from the right hand side and pack out the left.
