I heard something just befor I parked it the last time I road it (been rideing the Harley last 2 weeks).
Today took it to work 50 mile. Well when sitting idealing can hear like a pop out of the right muffler, now get out and rideing can't really hear anything out of the ordinary. Seem to have the same amount of power. Can't feel any exhause leakes but it feel diffrent out of the muffler. Haven't check vales in about 25,000 miles. I'm woundering coil, put new coil wires on about 2 months ago. I really haven't checked anything yet (in hay feild work right now after work). Got a procom.Rudy

maybe you need to adjust your mix screws

25,000 is way over due for a valve adjustment so should do that weather that has anything to do with the problem or not.

A pop as you describe could be a vacuum leak starting to appear or a small exhaust leak. Could also be some dirt in the carbs.
