What im talking about is my moped was on the stand not running. I turned the pedal forward by hand and i felt and heard the bell gear jerk slightly and catch. Like as if there is worn 1 way inside the bushing. Ive had it 2 years and yesterday was first time it done that. i know what caused it. Dumb ass me going up hill slight upgrade and it stressed the clutch drive on the crankshaft im hoping i didnt damage splines/teeth on crankshaft.
