Considering it was my son that sold these and they were fine when sold it appears the F***ups that bought them don't know how to ride or take care of them. If they were this f***up why did you buy it you f***ing morons. Timing chains don't just "fall" off. An idiot musta been at the wheel. Drop your zippers and give your brains some air dude-God did put your brains in the "little" one. I seen it!!!!
