The first prescribed value n is a predetermined revolution number smaller than a present revolution number and the clutch-on revolution number n is the present revolution number, and the revolution number control system controls the revolution number by operating the ignition timing delay controlling means when a throttle opening sensor does not detect a change in the throttle opening.
