Recently put in a new reverse gearbox and all new gears and bolted everything up, but the engine just revs up with little speed to atv. I took the belt cover off and checked the belt pulley clutch , the clutch pulley is not engaging or disengaging . I took the pulley off and put another one on but it does the same thing. I also had to take the forward gearbox off to put on the reverse gearbox, did I put something on wrong, any help would be appreciated. Thank you, Donna

 

I found out from John at Raceway why the engine would only rev up and the atv would not go. It has six weights that look like spacers but are weights that have to be inserted behind the front belt pulley for the centrifical clutch. these are for balance. Another one for John at Raceway. Thanks Donna
