I've got a high pitched buzz/whine in 1st and 2nd @ 5-8 k RPM that disappears when I engage the clutch. Thenoise itself sounds similar to the ignition key buzz but a little higher in frequency. It dissapears at higher RPM in 1st and 2nd or alltogether in 3rd through 6th gears. I am guilty of missing a few shifts between 1st and 2nd at the track while hard on the throttle. Shift fork, dogs, any ideas. Am I mis-interpreting the noise and could this be something else? The thing that points me to the tranny is the fact that it quits when I pull the clutch. Can I continue to ride?
