Question about 2002 Yamaha YZ 426 F
1 through 4 is ok.but in 5th bike revs, but nothing to rear wheel seems to slip. New rings, piston, power valve fitted. Bike shop seems to think the 5 th gear is stripped because this is an apparent problem with the YZ. Thanks 2002 YZ426F is good 1 thru 4, when I shift into 5th, it goes in and out of the gear, almost seems like it is running out of gas, or the gear is slipping, if I baby it, it works, as soon as I get on it in 5th only, it starts slipping, could this be the shifting fork?
Do an oil change. If the gear were stripped there will be lots of metal particles in the oil. More than likely the fork is slightly bent such that the slider for fifth gear is just barely engaging. Put pressure on it by increased throttle and it pops out.
