after months of perfect running (besides maybe a little inconsistent idling) my moped decided to backfire and stop reving up. when i killed the engine, I was not able to start it up again. I have changed the spark plug, with no different results. I'm not sure what the part is called that houses the electrical components, but whatever that is (by the pedals on the right side of the bike) I cannot get that open. Any comments on what the hell might be wrong w/ this bike? or how to get that piece open?
I'd really appreciate any suggestions.
