Bike is a 08 yz250f with about 25 hours. Son still rides it like a 125 using more clutch than most 4t riders. this is what he told me. "When I am on the gate waiting for the drop, bike in 2nd gear, clutch pulled in, revving up for the start, bike feels likes it's already pulling forward even with lever pulled in all the way." All stock clutch, adjusted properly. Does this indicate wear on a SPECIFIC part in the clutch or just to check it all?
