My Xr650r clutch slips from mid to high rev badly. I've adjusted the clutch to have as much freeplay as possible and it helps a little. The bike only has 800 or so miles on it. We do alot of tight trails though. I was curious if anyone has had any issues with this. Do I need HD springs to correct the problem. Or do I need a new clutch. It's fine upon takeoff but go to romp on her and she just sits there. Really annoying.
