I installed my new motor on my bike and rode down a hill to release the clutch to get it gonig and when I did: The motor was yanked to the side of the drive chain, the cdi cord split, my new #41 chain split and another car ran over my fuel filter. I had gone with a standard front mount but a new rear mount design that only involves one stud but I thought was still very secure, I did this because the standard rear mount would poke the chain a lot. So my question is, is there something I need to do to the sprocket like grease it or something? Or did this happen because of my mounting technique? If so, how can I make it so the rear stud doesn't touch the chain? (Again, the bolt that goes on that stud pokes out and tocuhes the chain)
