So I posted the other day about my gear position sensor being wonky, often showing no gear.
Ahead of replacing it I put my bike in dealer mode and went for a ride, took about 35 miles before the FI light came on with a C65 code - which is listed as idle speed out of range, which is odd as I was doing 40 in 5th at the time, letting engine braking slow me into a 30 zone.
Haynes book is useless for this code it seems, service manual lists Air passage clogged, STVA is fixed, Idle speed malfunction, Air leakage or ECM malfunction as possible causes. The bike idles fine, and seems to be running fine, fuel economy hasn't changed.
Probably just going to take it to a dealer as I can foresee myself just throwing money at parts if I work on it myself.
edit - I should add, I've searched this forum and others, my clutch operation is normal also, safety switch is doing it's thing so I don't suspect that.
