I have had starter problems for the last year. It would click occasionally. I finally took the solenoid off last night and see the problem. It has an actuator that slams a copper disk across two copper plates to make the connection. I can see where all the clicks have left burnt pock marks on the disk in different spots.
P.S. The last bike to leave me on the side of the road was a Boss Hoss Trike. It was 100 degrees and humid and I had my wife with me. I was 80 miles down the Natchez Trace from the start in Memphis. The motor was a 350 ZZ4. The alternator quit and as soon as the battery drained it started missing and then died. I am sad to say it left my garage within a few weeks.
