Abstract: An improved clutch pack is disclosed. The clutch pack incorporates liners, improved driving friction disks and driven disks where the thickness of the improved driving friction disks and driven disks are selected in order to allow more driving friction disks and more driven disks to be used within the improved clutch pack while maintaining approximately the same overall height as compared to the standard clutch pack the vehicles clutch system was designed for.

Abstract: An improved expanding friction disk for use in a clutch of a power transmission system. The improved expanding friction disk accommodates multiple clutch pack configurations including clutch packs utilizing novel improved friction disks, is compatible with wear liners and operates with reduced friction including a reduced difference between the static and dynamic coefficients of friction in the ramp mechanism.

Abstract: An improved friction plate is disclosed. The friction plate incorporates friction pads having substantially V Shaped Grooves having an angle offset to the axis of rotation to improve oil flow characteristics to the center of the friction plate to reduce parasitic drag when the clutch system is in a disengaged state. The improved friction pad design optionally incorporates a V shaped groove extending to the tab portion of the friction plate to improve the capture of oil as the friction plate rotates through an oil bath.

Abstract: A novel clutch separator plate is disclosed. The improved clutch separator plate incorporates openings which pass over the friction pads of a friction plate to improved thermal stability, reduce drag and provide consistent and positive engagement.

Abstract: An adjuster is disclosed, to be placed “in-line” to a clutch disengagement system. The adjuster provides a means for lifting the pressure plate above the clutch pack without significantly affecting the operation or feel of the clutch disengagement system to the operator. Such an adjuster is particularly well suited for use with an automatic centrifugal clutch incorporating a friction disk that expands when rotated above a threshold speed.

Abstract: A novel adjustable slave cylinder is disclosed. The improved slave cylinder is particularly well suited for use with a clutch incorporating an expanding friction disk. The adjustable slave cylinder provides a means for adjusting a clutch pressure plate's position via an adjustment mechanism external to the inside of an engine.

Abstract: An improved liner and friction disk for a clutch basket is disclosed. The improved liner is easily retrofitted into a typical clutch basket and is held in place without fasteners or adhesives or special changes to the clutch basket. The improved liner is held in place without consideration to the outer diameter of the basket allowing the liner to work with a wider range of clutch basket designs and sizes. The liner provides an improved wear surface for the clutch basket's engagement surface with the driving friction surface. A friction disk with tabs adapted to fit inside the narrowed space provided by the improved liner is also disclosed.

Abstract: A clutch apparatus is disclosed having concentrically spaced inner and outer clutches. The inner and outer clutches are coupled for rotation via a coupling ring. The present invention is well suited to a configuration wherein one of the clutches is dynamically actuated and one of the clutches is manually disengageable by the operator using a clutch lever. In this configuration, the operation of the clutch lever by the operator is unaffected by the dynamically actuated clutch. The concentric configuration of the clutches is beneficial in allowing the improved clutch to occupy a similar space compared to a traditional clutch mechanism.

Abstract: An adjustable axle assembly for the front fork of a motorcycle. In the preferred embodiment, the axle is received within an eccentric axle carrier which in turn is received within mounting holes in the front fork. The mounting holes utilize a pinch bolts as a clamping method to secure the eccentric axle carrier within the fork. In the preferred embodiment, loosening the pinch bolts allows the eccentric axle carrier to be rotated effectively moving the position of the wheel relative to the fork. Moving the wheel forward and backwards changes the trail characteristic of the motorcycle's geometry.

Abstract: An apparatus and system are disclosed for automatic centrifugal engagement of a clutch incorporating a friction disk that expands when rotated above a threshold speed. The apparatus may include a clutch basket, a clutch pack capable of coupling the clutch basket with a center clutch, a pressure plate that may be easily adjusted to create a gap between the pressure plate and the clutch pack and an expanding friction disk assembly that may take the place of one or more friction disks. The assembly expands under centrifugal force to provide automatic engagement of the clutch. A mechanism is provided to manually override the automatic engagement of the clutch with a clutch lever and with improved operational performance of the clutch lever versus previous automatic clutch systems.

Abstract: An alternative cap for an integrated reservoir brake master cylinder. The improved cap provides an input for a second brake master cylinder and a novel sealing means. The sealing means bypasses the integrated brake reservoir's sight window and cap allowing hydraulic pressure from a second master cylinder to actuate the rear brake while preventing the integrated brake reservoirs sight window or cap from leaking oil under hydraulic pressure.
