This is the stock clutch from my 95 zrt 800. The clutch was stuck closed when I bought it. I could get it open buy jamming a 2x4 in where the belt goes. But, as soon as I start it up (w/no belt on) and rev it to where I could see the clutch close it would never open back up. I have a new clutch on my sled now I was just wondering if I could rebuild the old one for a spare or is this one to far gone to rebuild?
