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.

An intake system for a motorcycle having an engine. The intake system includes an air box having a first opening for receiving intake air and a second opening for supplying the intake air from the air box to a throttle assembly of the engine. A filter element is disposed within the air box for separating debris from the intake air. A valve is disposed within the air box between the filter element and the second opening. The valve is movable to provide a variable restriction to intake air flow through the air box.
