Yesterday I was testing my 525 after I installed the JD jetting kit and diaphragm kit. Everything felt great until I decided to do a small brake stand in the street. I spun the tires for 2 seconds then rolled out of it. A few minutes later, I pulled into my garage and the quad stalled when I had the clutch pulled in. I tried to start it while in 1st w/ the clutch pulled in, but it rolled forward. The clutch won't fully release, the lever feels normal, and the shifter is hard to move sometimes. I bled the clutch but it didn't help. What might be the problem? Busted spring? If the clutch needs to be replaced, I'd like to replace it with a good racing clutch. Any suggestions?
