When I took my little monster DD bike down to Brands I could hear what I would describe as a whine when dropping from 5th gear down to 4th. I also had an issue in that when cold the clutch was ok, but get the bike warm and suddenly the clutch lever had to be pulled all the way back to the bar.
At Mallory the same noise was obvious when going into the hairpin. When releasing the clutch there was the whine again and then ok. The same when dropping to fourth for gerrards as well, in would come the whine after releasing the lever.
Before I start I want to know what I am letting myself in for. I am guessing the clutch plates will need to come out and be inspected visually for discolouration and also measured for wear?
However when I have had worn plates the clutch has been consistant is there some way that pressure may be building up but not returning after the lever is released or the other way round. Just seems like the clutch is slipping when I disengage it when hot, but when cold the point when you release it is in a sensible position.
