OK. Here's a new one on me. When I go from sea level to 7 or 8 thousand feet over the Sierra Nevadas to Lake Tahoe at 6,000 ft my clutch will not completely disengage when I pull the lever all the way in. Shifting becomes notchy and abrupt and sitting at a stand still in first with the clutch pulled in the bike still wants to go, I have to hold it back with my feet. When I come back to sea level, it's fine. Any ideas ? And yes I had the dealer change and bleed my clutch fluid last time it happened last year but this year its doing it again.
