Another culprit happens at the other end of the throttle cable. Down at the carburetor, the cable gets stuck, so even when you rotate the grip to ease up on the throttle, it still stays open.

Before every ride, check both ends of the throttle cable for debris that might cause your throttle to stick. Be sure to check around the handlebar and the top of the throttle tube.
