Hey all, I have noticed recently a high pitched whine as I am rolling to a stop in gear...when I press the clutch in, the whine goes away (and does not happen if I get back into gear). I actually noticed it at the track recently and it was loud enough for me to hear it through my helmet. Usually on the street it is less noticeable. Thought it was the AC but happens regardless of whether the compressor is on or off. Thought it might be the fuel pump but the sound went away on clutch disengagement.

Opinions?
