Mr. Clean said:If it sticks in the hollow shaft it came out of the answer is yes. I would straighten it or replace it if I were you. I remember on those old bikes that the clutch would slip if the plates wore out so thin that the pressure plate would bottom out on the shaft you pictured before the plates tightened up. A cheap fix for this is to grind this same shaft shorter until it allowed the plates to tighten. Hope this helps. Mr. Clean
Mr. Clean said:Does the bent shaft move freely in it's hollow shaft? Does the cable prevent full engagement? Is the clutch assembled correctly? All these will make the clutch slip.
