Re: heres a story for you
hey lilhudi, welcome aboard
the same thing happened when me and me bro built his bike
turned out the chain tensioner was not staying straight. we fixed that and made sure the sprocket was good and straight, and aligned with the motor sprocket. haven't had any problems with the chain since.
good luck and happy motoring
