Abstract: An improved clutch basket assembly is disclosed. The improved clutch basket assembly provides improved wear resistance at the interfaces between friction discs and a clutch basket housing while allowing an operator to have improved clutch lever control and modulation when manually engaging or disengaging the clutch system. The improved clutch basket assembly includes a generally cylindrical clutch basket having a sidewall, a closed first end and an open second end. A plurality of removable pins is attached to the sidewall. A plurality of frictions disks is mounted in said clutch basket. The friction disks each have a plurality of positioning tabs extending out from a periphery of each of the friction disks. The positioning tabs are configured for engagement with at least one adjacent removable pin removably attached to the sidewall.

Abstract: An improved master cylinder for use with a hydraulic clutch or hydraulic brake system. The master cylinder has a master cylinder body defining a bore. A piston is configured to slide in the bore when an actuation lever is compressed by a user. Sliding of the piston as a result of the depression of the lever causes the piston to depress a spring and to increase hydraulic pressure in the hydraulic line leading to the brake or clutch. A spring is configured to return the piston when pressure is released from the actuation lever. The master cylinder body in some embodiments is configured for lateral position adjustment relative to a mounting bracket. In some embodiments the master cylinder has a reservoir. The reservoir can be oriented at a tilted angle relative to the body of the master cylinder. In further embodiments the master cylinder has an outlet nut that is configured for attachment to the hydraulic line.

Abstract: An improved adjuster for a clutch having an expanding friction disk. The improved adjuster allows desirable characteristics of a clutch pressure plate to be maintained while allowing an operator to bias the pressure plate into proper position to accommodate the function of the expanding friction disk.

Abstract: An improved clutch hub assembly is disclosed. The improved clutch hub assembly provides improved wear resistance at the interfaces between separator plates and a clutch hub while allowing an operator to have improved clutch lever control and modulation when manually engaging or disengaging the clutch system.
