So I have a 2006 tw, fairly stock, used with 2000+ miles off road on it. A woman had it before i got it and i think that she may have been riding the clutch a lot. when on the highway in 5th gear I can feel the clutch slipping a lot... I already loosened the clutch cable so that it wouldn't put any force ont he plates but it still isn't better. Should I (could I even) tighten the springs on the clutch? What about new clutch plates? Where can I get these if i need to get a new assembly or plates?
