Slave Clutch

Post by Poohman » Thu Mar 20, 2014 5:46 pm

Hey everyone I have done a basic rebuild of the slave clutch, which was the rubber rings and seals on the cylinder. I rode it once and got on it the next day and all the fluid is gone again. Which I was told is going into the engine????? I am not sure if the cylinder piston is wore out or is there something else that I am missing? Going to take it apart again and see if there is something wrong with the seals and rubber ring. Any Ideas out there? Thanks and I really appreciate all the help I can get!
