Just got out of work and i waS riding home when i noticed the red warning light was on:headshake. not sure if it was on from the beginning but it did stay on for a good 10 minutes before i got home and turned it off. put my bike up on the stand and restarted her, no light. im about to go rip down the road and back to see if it comes on again. has anyone else had that happen or know what it could be?
