A revolution number control system includes ignition timing delay controlling means for delaying ignition timing from the ignition advance amount n at a first prescribed value n2 when the engine revolution number NE is between the first prescribed value n2 and a clutch-on revolution number n4. The first prescribed value n2 is a predetermined revolution number smaller than a preset revolution number and the clutch-on revolution number n4 is the preset revolution number, and the revolution number control system 40 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.
