a fuel tank that stores fuel;
an engine;
an intake passage that supplies air to the engine;
a fuel supply device that is connected to the fuel tank and supplies the fuel to the intake passage;
an electronically controlled opening/closing valve that opens and closes the intake passage;
a control unit that controls the opening/closing valve;
a power source that supplies electric power to the control unit;
a main switch that turns on/off the power source;
an engine start switch that starts the engine; and
a rotation speed sensor that detects a rotation speed of the engine and outputs the detected rotation speed of the engine
to the control unit, wherein
the control unit comprises:
a valve drive unit that causes the opening/closing valve to perform a determined initial operation when an initial operation
signal is input; and
an output unit that outputs the initial operation signal to the valve drive unit if a determined condition is satisfied when
the main switch is turned on, and if the determined condition is not satisfied when the main switch is turned on, outputs
the initial operation signal to the valve drive unit when the rotation speed of the engine has reached a determined rotation
speed range after the engine has been started.
