  • Cylinder deactivation for a motorcycle engine
    Patent number: 7488273
    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.
    Type: Grant

  • Motorcycle dynamic exhaust system
    Patent number: 7347045
    Abstract: The present invention provides a method of operating a dynamic exhaust system of a motorcycle engine. The method includes providing a valve in the exhaust system that is movable to direct exhaust gases between a first flow path through the exhaust system and a second flow path through the exhaust system. The method includes actuating the valve at a first speed to redirect exhaust gases from the first flow path to the second flow path and actuating the valve at a second speed greater than the first speed to redirect exhaust gases from the second flow path to the first flow path.

  • Motorcycle exhaust system
    Patent number: 6804954
    Abstract: An exhaust system for use with a four-stroke engine having first and second cylinders. The cylinders generate exhaust pulses at uneven time intervals with respect to each other. The exhaust system includes a muffler and first and second exhaust pipes that communicate between the mufflers and the first and second cylinders, respectively. The first and second pipes being sized and shaped to deliver the exhaust pulses to the muffler at even time intervals with respect to each other.
