I have a friend with a 1999 shee. Yesterday we were playing around in the snow and his clutch lever went limp. When moving the clutch handle in and out it does move the clutch shaft that goes into the case (so cable is fine). It does feel like there is nothing grabing. You can even turn the shaft back and fourth with your hand very easy. Any ideas on what to check for? Thanks in advance!!!
