Abstract
A power control device and method for a motorcycle. The power control device controls the power of the motorcycle engine in predetermined situations. The power control device controls the power output of the engine while maintaining an optimal air-to-fuel ratio to prevent backfires and misfires during combustion. In one embodiment, the power control device reduces the airflow to the engine by rotating a throttle valve. The amount of fuel delivered to the engine is also reduced corresponding to the position of the throttle valve. By reducing the amount of fuel delivered to the engine based upon the amount of airflow to the engine, the air-to-fuel ratio within the engine remains optimal for combustion. The throttle valve can be rotated by the operator and by the power control device. The position of the throttle plate and corresponding power output of the engine is controlled by the operator until overridden by the power control device.
