Mine's a 2000 so its probably not the exact issue you have. Did the noise vary with load/throttle, as in louder at steady state cruise than during accel/decel? Or just off idle? Mine sounds to me like it is top end but it is quiet at idle, and I haven't a clue how to trace down a noise like that while underway. Can you tell looking at the compensator? (wear marks, etc?)

My 07 has been making weird noises on that side, I got the Extended Warrenty, gonna look into this issue & upgrade.

Makes me wonder what year is the highest quality bike, all being somewhat subjective of course. There are quite a few used Twinkies around with low miles that have been upgraded to gear driven cams, prolly what I'll end up with. Another great writeup TL, thanks. -- John

Doubt it. The suspect compensator came out in '06. > Did the noise vary with load/throttle, as in louder at steady state cruise > than during accel/decel? Or just off idle?

Can you tell looking at the compensator? > (wear marks, etc?) No clue. Mine was only audible at or just above idle as the RPMs were decreasing. Anything above 1100 RPMs and I doubt if you'd hear it as there's to many other things thrashing around making noise. 112 <--- maybe it's your brake pads |
