OK, I have the Dual force clutch and it worked slicker than shit for the first 5,000 miles. Then it started to get a little harder to hit the gears smoothly. 10,000 miles on it and the bastard hardly wants to go into reverse. I know for a fact that I have PLENTY of life left in it because I had this same problem before. I think some sort of shim is what I need. Where can I get a shim kit?
