You can hook up an OBD II code reader (pretty standard car code reader)and get the code (most auto parts stores will hook you up for free). You plug is under the rider's seat in front of the battery. The reader will offer the option to clear the code once read. IF there is an unaddressed problem, the light will come back on.
If there really is nothing wrong, 3 heat cycles will clear the code.
Check your battery cables and tighten them if needed. That will sometimes do it.
My light went on the first cold ride I took. It turned out to be an O2 sensor. I washed the bike before the ride. I am not sure if it was related. The light has not come back on after clearing the code.
Hope this helps
I would just do 3 heat cycles to clear the code. Probably a low Battery, they do that stuff as they are really power sensitive, run up to temp and turn off three times, then keep her on a battery maintainer like optimate.
