This is the same issue I have but my headlight goes out. Turned out to be a bad ground wire on the main harness, but I am having a *$#@ of a time finding the bastard. I have a feeling that the wire is broken some place near the head tube. This could be the same issue but different wire. If it is broken it could be acting like the kill switch is open keeping the bike from starting. Thats my 2 cents.....
