While sitting at a traffic light on the way to work the other morning. Motor started knocking while at idle at the said light and I rode it in to work (1 mile). Left work and bike started and sounded fine. Got almost home and knock started. Its clearly a knock that only happens when warm. Its not something that you have to lean over the hear, Its a KNOCK! Does it at idle and revved up. Pulled primary cover and the compensator nut is tight and all seems well in the Primary. 2003 Road King with a 98" Hillside kit and 57 cams. S.E. cam plate and oil pump with 10K miles. Tried a stethoscope and the knock is so loud it is hard to isolate. This came on with no warning other than it starting to act up at the traffic light.. I may tear into the cam chest just to see what may be happening in there....Ideas?
TIA!
