I have an 03 RT with 43,000 miles and about a month ago I noticed a rattling sound from under my pegs on idle. When I pull in the clutch it disappears. I was at my mechanic 2 weeks ago and he said it was on the louder side of normal and that he said to come back if it got any louder. If memory serves I believe he said it could be the master cylinder for the clutch or a bearing. The bike runs fine but after a 100 mile jaunt this morning the rattle got twice as loud and can now be heard as a whine in first and second. Is this ringing any bells with any of you?
