05 doesn't rev out to redline
Helped a friend build an 05. Pretty much same thing as mine, but with a Wiseco piston instead of stock. HRC cam, stock carb (40 pilot 170 main) Yoshi exhaust and no airbox lid. Carb is clean as a whistle and gas is a week old.
Valves are shimmed at .006 and .011 and decompression is set to 75 psi while kicking @ wfo throttle. Cam timing is dead on. Idles great. I don't think it would kick over in one kick if it was off.
Tried swapping my ignition module and the coil pack off of my 05. No change. The decompression was set wrong before, was over 110 psi, no change after dropping it to 75. There is a brand new NGK plug in it. New flywheel key too as the old one was worn.
It's almost as if it won't run up to the end of the RPM's. No matter what throttle position, full, mid, whatever, it hits a certain point and it starts backfiring and shooting flames.
I think the stator in his bike is aftermarket. And I know how suspect they can be. This is where I keep coming back to as the problem. Am I on the right track?
