based on the amount of times i've read posts exactly like this one, i would say it is one of 2 things. first check to make sure your battery cables are tight, they are notorius for loosening up and causing the problems you decribing. the other would be doing the ground fix. when these bikes were built the electrical grounds were attached to the frame over the paint. these bikes need to be grounded well in order to operate correctly. if you need more info on the ground fix let me know and i'll send you a link. but definetly check your cables first. good luck and ride safe.
problem fixed!!! A couple of turns with a screwdriver and its all good. thanks again Crewsn and Brad
