ABSTRACT:
A clutch cable lever operating system having a cable adjusting mechanism including a clamp for mounting the system on the handlebars of a motorcycle. The clutch cable lever fulcrum mounting flange to allow more or less free travel when the cable operating lever is used. The clutch cable adjusting mechanism is comprised of a coarse sleeve threaded into a cable adjusting cylinder that abuts the end of a cable outer sleeve. A manually adjusted threaded star nut or thumb wheel is fitted in a slot in the cable adjusting cylinder and threads on the coarse threaded sleeve. Rotation of the threaded star nut or thumb wheel incrementally extends or retracts the coarse threaded sleeve abutting the end of cable to adjust the slack that occurs when clutch plates expand due to heat. A resilient washer in an annulus intersecting the threads in the star nut or thumb wheel prevents free movement of the star nut on the coarse threaded sleeve to maintain the adjusted position. The resilient washer prevents free movement of the star nut from an adjusted position which might be caused by vibration during operation of a motorcycle.
