so this morning took off to work and 2 or 3 times my 04 didnt want to upshift. after a few tries it finally did and them came out of it without happening again. does the fluid need to be warm to operate correctly? I am in maine and it was about 35 degrees so I am wondering if it just needed to warm up. bike has 31k on it and I have never changed the clutch fluid, but the dealer may have (bought it with 28k) and previous owner was super anal about keeping the bike clean and serviced. thanks
