For you, long distance riders, a new throttle control a little bit different from the ones you may know. This one is supposed to be extremely simple to install, 15 minutes on stock grips (different models for Harley-Davidson & Metrics) and a little bit longer when using after-market grips. You know the objective: reduce your fatigue and strain on hand and wrist. While cruising, the rider is able to remove hand from throttle grip, throttle opening will remain as set. The friction nut has a left-hand thread. It must be adjusted so that it makes light contact with the rubber throttle sleeve. To Engage: While rolling on the throttle, the friction nut can be gripped between the small finger and palm of hand. This action tightens the nut and provides sufficient friction to set throttle to the desired opening. The friction is such that the rider may still open and close the throttle. It simply has a slight stiffness to it. To Disengage: While rolling off the throttle, grip friction nut between small finger and palm of hand. The throttle should open and snap closed freely when correctly disengaged. Note: The Grub Screw is set to provide the necessary resistance on thread of friction nut. This may be adjusted periodically to take up wear. Several designs in chrome & black. Kaoko Cruise control.
