Chrome Solenoid button replaces the stock cover on '89 and later 1.2 kw, 1.4kw, and 1.75kw starters.  Same part used on all Thunderfire 1.4 and 1.75 kw starters.  This button bypasses the starter handlebar switch and relay.  Great for backup use or custom use.  Great for Indian and Harley Davidson motorcycles.
