I traded a motor a while back with a member on here, supposedly it would not shift past third gear. I was messing with it tonight and found that if I put pressure on the clutch lifter plate I could shift it through all gears if I spun the sprocket in between shifts. When i initially got the motor I thought it would be a bent shift fork, now I'm not sure. Damaged shift star? Where should I go from here? I'm working on a tight budget so if I don't have to tear it down all the way I don't want to.
