Abstract: A method of reducing heat produced by an internal combustion engine in a motorcycle. The method includes supplying fuel pulses to a combustion chamber at least once per engine cycle (consecutive engine cycles defining a series of consecutive fuel pulses), operating the motorcycle at a low speed condition, and withholding at least a portion of at least one fuel pulse from at least one subsequent engine cycle to the combustion chamber when operating the motorcycle at the low speed condition.

Abstract: A side cover assembly configured for use with a motorcycle. The side cover assembly includes a side cover, an inlet, an outlet vent, and a fan assembly. The side cover is adapted to be coupled to the motorcycle, and the side cover includes an interior surface facing an interior side and adapted to face at least a portion of the motorcycle, and an exterior surface facing an exterior side opposite the interior side. The inlet and outlet vent are at least partially defined by the side cover. The fan assembly is coupled to the side cover, and the fan assembly is operable to draw air from the exterior side and into the interior side through the inlet and discharge at least a portion of the air from the interior side to the exterior side through the outlet vent.
