So I just picked up a 17x for my son, and when you let off the clutch the bike wants to roll. Correct me if I'm wrong, but the sport clutch from what I understand isn't supposed to move until you get on the throttle. I have tried to adjust the clutch many times, and nothing I do keeps it from not rolling on its own. I can back it off enough where it wont move, but also wont move giving it some gas as well. Does it sound like a bad clutch, or just not adjusting it correctly. Any tips would be great. I've tried to back the screw out both directions until it doesn't roll no more. Adjust the lever, and get same results each time. I have adjusted according to the repair manual. Also if you all think the clutch needs replaced, how hard of a job is it. It has fresh oil in it as well. Can the idle be to low causing this? Thanks.
