my '00 road king,,,21000 miles,,,, has done this 3 times,,,nearest i can figure thru the service manual is slight backfire on the fly wheel,,,sounds like a cough ,,,on cranking,,,which triggers crank position sensor,,,the first time i paid 28 bucks to scan it ,,,they cleared the code and said dont worry about it,,,,the 3rd time i was listening close enough that i heard the cough ,,,it clears automaticly after 50 starts,,,the 2nd time i was on a long trip so i didnt bother me for long because of so many starts,,the light bugs the heck out of me too
