seems to me there is an odd voltage spike at some point. you may want to check the voltage going to the headlight with a multimeter while the engine is running although it appears to be a very specific problem since you didnĀ“t say anything about the turn signals or brake light. i purchased this bike just yesterday and have had a blast on it so far...except when it stalled out and took way too long to get it kickstarted again. i have the repair manual ordered for this bike but if you could tell me where i might find the crankcase oil drain plug (i found the oil filter) it would be much appreciated. one of the plugs that i removed in thinking it may be the crankcase plug was the gear box plug. also would you please tell me where to find the filling plug for the gearbox. thanks, happy riding. you/anyone can reply by email if you wish. rickm@3web.net
