Recently I've noticed when seriously twisting the throttle (not necessarily downshifting), it appears the clutch is slipping slightly as the bike accelerates. There is plenty of play at the clutch lever. Is this a clutch spring issue or sign of something worse? Never noticed that happening before the 904. I may have noticed it only rarely the last couple of years. It is happening a lot more lately.
The only oil used in the bike has been Triumph recommended oil bought from my Triumph dealer. Appreciate any input.
