Re: How do I stop breaking spokes?
Is the rag joint installed correctly? Are the spokes sandwiched between the rubber parts or are you trying to run it with the spokes touching the metal components of the sprocket adapter?
If the rag joint (rubber sandwich) is correct then as was stated above, check your wheel for trueness and spoke tension. If you don't feel competent with trueing your own wheels a bicycle shop can do that for you. Loose or misadjusted spokes will break, even on a pedal powerd bike.
Another thought; are you using the kill switch or choke to stop the engine or simply letting the clutch out to shut it down?
