OK...my /09 Ultra has developed a squeal..squeek? that seems to be coming from the rear on the right side of the bike. It sounds like the noise a belt might make when slipping on it's pulley (that's about the best way I can describe the noise). Now this only seems to occur after the bike is warmed up and is not noticeable when the engine is under load but is noticeable on a trailing throttle and only when decelerating from highway speeds. Around town I don't hear it. I can't narrow in on the source of the sound and have eyeballed the bike carefully looking for anything that might be loose, etc. but have found nothing. This has been going on for several months and the bike has performed flawlessly throughout. The clutch is properly adjusted, the drive belt has the proper tension, all fluids are correct...I'm stumped. Any and all ideas will be welcomed.
