    the bucking bar on my 66cc 2 stroke is too long, ever since i took the clutch apart to see if the pads where gone and put it back toghether i noticed it sticks out to far, about 7,8mm too much so i cant put the clutch cover on, i know a simple solution would be just to cut the bar but i wanna know wat use think first

    Something must be wrong, if you do replace the bar DON'T cut yours. Get a drill bit the same size and grind it down to the length you need.

    Are there 2 ball bearings inside your transmission shaft? There should only be one.
    7 to 8mm is about 5/16" which is the diameter of the bearing that goes in the shaft which also, coincidentally, is the length that you say the shaft is sticking out too far.

    It was working or should I say fitted together. Problem only after he took the clutch apart.

    How bizarre!
    I am a bit leery at the idea of cutting something that originally fit before the assembly was torn down and reassembled. The drill bit idea is awesome as the resulting bucking bar will be leaps and bounds better than the factory one, and the original equipment bucking bar will still be intact if needed down the road. Still, if all the ingredients of the clutch assembly have not changed, and everything was assembled to original spec, something is not right here. Metal does not grow all by itself.
    I wish you the best of luck with your repair, ae86lad. Something has definitely gone screwy in there somewhere...

    ae86lad, as mentioned, do not cut the bar. Something is weird here. Is it possible that, as GearNut suggests, you have two ball bearings in place instead of one?

    Hey my bucking bar goes in all the way I think the bearing is gone. How can I fix this.
