yeah my rapter one way bearing just went. When i went to turn it over the flywheel would just spin freely instead of turning over the rest of the motor. So i finally just got pissed off and bought a whole L and A designs one way kit with all the gaskets, gears and everything else thats needed. I got mine from RaptorCam over on bluetraxx for about 230$. Great guy to deal with. Shipping was also very fast.
