A motorcycle includes a carburetor, an electronically controlled opening/closing valve that opens and closes an intake passage, an ECU that controls the opening/closing valve, a main switch, an engine start switch and a rotation speed sensor. The ECU causes the opening/closing valve to perform a determined initial operation if a determined condition is satisfied when the main switch is turned on. If the determined condition is not satisfied when the main switch is turned on, the determined initial operation is performed when the rotation speed of the engine has reached a determined rotation speed range after the engine has been started. To ensure that an initial operation of an opening/closing valve that opens and closes an intake passage is performed with a high degree of reliability.
