Interested to now if this is a problem, or a standard feature of the bike. I've had this bike a couple of months now, and i ride it rain or shine, hot or cold. I have noticed that I stall it at at the lights, and then i go to put on the heated grips later in the ride, nothing happens, as in no heat. The only way to get the grips going again, is to turn the key all the way off, remove it, restart the bike.... and then the grips work once more. Its only happened a few times, so i am not sure if the stall is whats tripping them up (the grips were not on when i stalled the bike), or if the key out and restart is the solution, or if its somthing else entirely. Normal? Warranty?
