Saw a 2004 Chopper at BBBQ in Fayetteville, Ark. that just got a click, click, when trying to start. He opened his starter, cleaned the contacts and still got the click. What he found was a bad soldered connecting to the starter solenoid. Worked fine after he fixed that. Take the cover cap off the starter, check/clean the starter contacts, and manually push in the solenoid. If the starter turns over, you've got a bad connection to the starter solenoid.
