Many years ago I considered a similar set-up for actuating a starter solenoid eliminator on one of my '65s.
The first thing that became apparent was that the mechanism had to operate when the grip was twisted forward, not backward. Twisting backward, or toward the rider, is the natural direction that the g-forces of operation encourage. That's why advance and throttle controls operate that way.
If your clutch operated by twisting toward you, it would be very hard to hang on without re-dis-engaging it.
So a stock advance control using 'music' wire would work for a clutch, if you reverse its direction with a later spiral.

or stretches and breaks! another name for music wire is piano wire or guitar string, good stuff. You can tow a locomotive with it and it will flex forever before it work hardens and breaks.Cotten wrote:"Music wire" also refers to the original design of wire control.
Beware of mild steel wire that easily kinks and bends.

The idea sounds good but the plastic parts are woefully inferior for this idea. Russell Mitchel at Exile cycles has a kit for late model clutches but it'd take major re-engineering to work on a shovel.

TWIST CLUTCH KIT
We offer a Left Twistgrip Assembly that is identical to the Internal Throttle Assembly, but with a reversed spiral for use on the left side of the bars. This can be used to pull a cable for many custom applications, but we frequently use it to activate the clutch. Additional parts are necessary to reduce the effort required at the grip, so we developed our complete Twist Clutch Assembly.
This kit comprises the Left Twistgrip Assembly plus a cut-to-length cable, clutch activator arm pulley and a cable anchor.

I don't see it as a mechanical or style advantage.
After watching the TV biker build shows where particpants and "builders" work so hard to make RUB bikes look cool I'll keep my stock Pan with foot clutch. It's cool without any effort. American Chopper does the "that looks cool, doesn't it?" thing way too much.
