Ok my friend has a bike its a 66cc black kit from speed demon bikes and for some reason it rolls forward with the clutch disengaged. That means it moves forward with the clutch out not squeezed. What could be causing this, the clutch arm articualtor has nothing to do with it I have checked for tightness and even disconnected the cable the bike still rolls forward without a clutch... I cannot get under the plate on the drive sprocket just yet it's has a stripped bolt it's really in there.... Could the wrist pin be jammed inside causing it to constantly be engaged?
