2007 Ultra has an intermittent problem. The engine will shut off when decelerating only. Also occasionally it is difficult to start. I have to crack the throttle a little bit when it doesn't want to start right away, then it will start, but if I let the throttle go back to closed it will stall. When the bike shuts off during decel, the oil light comes on. All I have to do is hit the starter button and it starts right up. I don't have to mess with the kill switch. Also, the IAC motor makes a grinding sound when shutting the bike off, but not when I turn it on.
