My 2001 RK has developed a nasty habit, the engine turns off while the bike is in motion, the flashers work, i know this because the last time it happened I was doing 70 mph at night with a bunch of traffic behind me. when the engine died and the headlight went out, i hit the flashers, turn the main switch to the off possition then back to the on possition and I got power back, then I popped the clutch and the engine turned back on, this has happend a few times and suspect that the main switch is on it's way out. Anyone out there have any thoughts on what could be causing this?
