Hello all. I have been lurking on this board for about a month trying to get my bike working correctly. I have tried all kinds of searches and cannot find a tip for my type of issue i'm having. First off, the only time the engine seems to have run correctly? is when the rear motor mounts loosen up then the thing runs real smooth and takes off and moves like a rocket (I assume this is how it is supposed to run anyways) Once I re-tighten the rear motor mount it then runs horrible. Will barely hit 20mph and will not stay idling. When I attempt to run full throttle it bogs down then kind of regains some power. It will keep doing this throughout the whole ride.
