Abstract: A clutch weight for a continuously variable transmission is disclosed. The clutch weight, in certain examples, includes a body having a first end having a pivot pin opening and a second end opposite the first end, a curvilinear surface disposed between the first end and the second end configured to engage a roller, and wherein the roller contacts the curvilinear surface at least at a first contact position, and a center of mass of the body disposed a distance Y from a center of the pivot pin opening and a distance X from the first contact position, and where a ratio of X to Y is in the range of between about 0.499 and 0.685.

Abstract: An auxiliary electronic fuel injection control apparatus for enhancing engine performance includes an isolation circuit connectable to a main control switch having an output voltage pulse and a ground. A pass-through switch is in electrical communication with the isolation circuit and is connectable to a fuel injector, the isolation circuit designed to substantially render the pass-through switch transparent to the main control switch. A re-driver switch is in electrical communication with the pass-through switch and is connectable to the fuel injector and the ground. An auxiliary controller is in electrical communication with the isolation circuit, the pass-through switch, the re-driver switch, and to the ground. The output voltage pulse triggers the auxiliary controller to turn the pass-through switch and the re-driver switch on and off to effectively alter a duration of current to the fuel injector.
