QUESTION: sportstertodd
Off course. I have had this bike for the last 30 years. granted it has sat for many years. It has shown problems with the starter button. I have by passed the starter button but it still will draw mor amps than the breaker will handle. I checked the wiring and cleaned the starter. I just keep drawing a blank on why it's doing this.

Answer
If its been sitting for a while will the motor roll over easily with the kick starter or could you try it electrically with the spark plugs out so there's no compression against the starter motor. Doing this will ensure the engine is not the cause of the high amp load drawed by the starter motor. Let me know what you find?
