PROBLEM TO BE SOLVED: To suppress an engine speed just after starting the engine by a starter. SOLUTION: When a main switch 34 is changed to a start position with a state where a brake is operated, the starter 21c is driven and the determination whether or not throttle opening at that time exceeds reference opening is determined by a throttle determination part 102. A engine speed determination part 103 determines where or not the engine speed exceeds a reference value NeCL set to an clutch-in speed or more. When the determination is affirmative, signals S1, S2 are respectively output from determination parts 102, 103. An ignition thinning part 104 outputs an ignition thinning instruction to an ignition circuit 101, when signals s1, s2 are output. Therefore, when the brake is operated and the starter is urged, and the throttle opening θTH is large, the engine speed Ne is limited within the reference value NeCL to suppress driving force. |
