My 2007 R1200RT has just over 112k miles on it now. After a ride this weekend I noticed that, especially in 1st and 2nd gears upon acceleration, that I am having a pronounced whirring sound as I ride.
The sound:
- is only evident with the clutch out (it goes away with the clutch held in)
- same sound with the bike in gear or in neutral, again depending on the clutch position
- is worse when the bike is cold
- seems to go away with engine braking but more pronounced with acceleration (that's the odd thing)
- not evident for the last 60k miles (or maybe my hearing changed? or I just noticed it now?)
I'm not experiencing any clutch slip, I don't have any oil spots under the bike, nor is there any leaking that I can see. The master clutch cylinder has the right amount of fluid.
To be sure: The sound is not evident with the bike engine off and rolling (the one time it pays to live on a steep hill). I drained the transmission oil and it came out clean without any metal flakes in the oil.
I can't seem to find any similar threads with this specific topic. A lot of people talk about the throw out bearing, but that would be the opposite - more noise with the clutch in??
Thanks for your insights!
