sorry in advance for a novice question . . . i adjusted the clutch by loosening the locknut and turning the adjustor counterclockwise until resistance was felt. turned adjustor clockwise 1/8 turn and tightened back up the lock nut. this was right from 08 crf70 owners manual. when i'm in first gear, the bike pulled itself, so i fiddled with the idle screw on the carb until it sounded right in neutral and did not pull in first. when in first if i lift the rear of the bike by hand the rear wheel does spin (pretty quickly). is this normal with the centrifugal or whatever you call it (stock) clutch?
