Does anyone know what it means when the reverse light flashes?
If the reverse light flashes (not flickers intemittenlty) while riding, the speed sensor (right rear of the engine case) is unplugged or malfunctioning. This has nothing to do with the reverse switch.
Also, grounding the green/white wire has nothing to do with bypassing the clutch switch , which is a black/yellow wire, to be able to start in gear.
