This is my cruise control for the GT200. It works in a friction mode and really does a good job. The only part is a yellow rubber gasket. A faucet washer will probably work too.

This is the off configuration

This is on. It may be crossed over where half the gasket is on the grip and pulled out and over the bar end. Same principal. There is a gap between the grip and bar end on the GT so I just let the gasket fill the gap.

How easy is it to pull the gasket into position while riding? Street? Highway?

Yikes! By the looks of it that setup seems unsafe. If you have to roll the washer out from the gap in the grip, you may be leaving yourself vulnerable with the inability to quickly react to changing riding situations.

Simple? Yes. Innovative? Yes. Safe? NO.

Old Harleys had no throttle return springs. You twisted the throttle and it stayed put. Older BMWs had a thumb screw that put friction on the throttle mechanism. I don't think this setup is unsafe. What do you think is unsafe about it? You still operate the throttle easily with the gasket in the "on" position. The friction just holds the throttle in place until you turn it. It is not locked in position.

If the throttle can be worked back and forth with the gasket/washer on, that's a little different but not as immdediate a response as simply letting go of the throttle. Even worse, if you have to actually roll the washer off to cancel the cruise control.

If the "old" Harleys and "older" BMWs "had" a similar setup, but no longer have them, perhaps there is a reason for it?

The "reason" is called electronic cruise control. Check this setup out; http://www.throttlemeister.com/black.html . It operates on the same principal of adding friction to overcome the throttle return spring.

Dude, if you don't think it is safe, stay away from it. Far away. Personally, I think cars are dangerous

It is very easy to roll the gasket on or off the grip.

A very simple solution.

I have been thinking about another spring on the carburettor, opposing the throttle spring for small throttle openings, so that I could ride no-hands for low speeds - up to 60kph, perhaps. But haven't figured where to attach it yet.

All my pre-PX Vespas would keep the throttle open when riding no-hands. The PX introduced that extra spring inside the handlebars. On my last PX I reversed the spring in the handlebars to get what I wanted.

All Harleys are "old", technologically speaking. The '08 H-Ds still have the friction lock. They can also be started in gear while on the side stand. Amazing to me that in this lawsuit happy country, H-Ds are not idiot proof (yet).

BTW, Mike, DON'T ad a spring in the open position! If you must, take the return spring off.
