Rough Ride at 8000
Ok so for those of you who saw my last post you already know, but i recently put a new kevlar racing clutch on my 1000f, and even with the old clutch, at 8000-9000 rpms, and only in first gear, the bike jerks a little, and then continues on towards 10k, and its not as if the engine in losing power, because it is solid all the way through. Origionally i though it was the old clutch, which did slip a lot but now i cant seem to figure this one out. It only jerks when i punch it wide open and in first gear, slow increase toward the 8000 mark doesnt cause it.

well it only does it in first, in neutral it doesn't, and if i hold the throttle it continues on. Its consistent almost every time. every so often i get lucky. I feels like something in the tranny gives up. Or maybe i break the rear tire for a split second. But it very well could be the ignition. The plugs are clean and new, i just would wonder why it is always at the 8k-9k range

8000 is where the max torque starts to come in - could it be a partial blockage in the fuel line, as opposed to an electrical problem ? Sometimes the petcock fuel filter can clog up - best answer is to reverse flow the fuel (a bicycle pump full of fuel) pumped up the line would soon tell you - if the blockage goes away for a time, drain the tank and clean the petcock.
Second option, could be a partially blocked tank breather. Try running the bike hard with the cap open (for a short time) and see if this helps. If it does, clean the tank breather.

Ok after riding today im fairly certain the engine is not the cause, i paid close attention to the rpms and feeling the engine you could say. The engine is consistent, and when something breaks loose and kicks back in it feels like pulling the clutch in and letting go again. The rpms kick up then back down. maybe like it finds itself in a false neutral for a split second. Then i was coming out of a turn from a intersection and opened it up and i was still in a light lean when i hit 8500 and it gave then kicked in, spinning the back tire a little. This is the first time i was in a light lean when it happened so im wondering if my rear tire is the cause. I have the suspension a little tight. It is a Shinko 005 tire.
