Went out to fire up my 2004 750cc Aero and when I pressed the starter button nothing. After pushing it two or three more times it caught and started right up. I let it warm up for awhile then shut it down and tried to re-start it. Same thing happened, I found that if I push the switch in and just sort of release the pressure just a little it catches and starts right up. My question is, within the switch are there contacts that can be cleaned up or am I looking at buying a new switch. Also how tricky is it to change the switch for a new one.
