Is Flip's version is always "on"?
I should have multi-quoted this along with my other post.
Yes, it's always on, but the degree of holdback (throttlelocking) is entirely varible by you. The amount of preload on the washers determins the amount of resistance. The preload is easily attained by loosening the clamp screws that secure the (right hand) switchousing and sliding it outward. When you slide it outward, you apply pressure to the washers through the end of the throttle spool.
I have mine set to a neutral throttle, that is, the throttle stays whever it's set and will gradually close from bumps in the road or vibration of the engine. It's just like the older HD's throttle was, no springback effect.
What induces wrist fatique on a trip, especially a trip on the expressway is that you are holding the throttle against the return spring and the steady pressure on your wrist causes it to cramp and loose circulation. if you remove the springback, you remove the steady pressure and the fatigue, plus, you can let go of the throttle momentarily to wigglr your hand and keep the circulation going without a sudden deceleration.

It's entirely possible to put a full function digitally encoded cruise control unit on the R3. I have one sitting in the shop on the shelf but the problem is that you need sufficient vacuum to pull the servo (that the cruise control unit actuates and the R3 don't make sufficient vacuum to hold the servo at a steady rate of speed).
The unit is an Audiovox CSS unit. They are about 100 bucks and you can adapt them to the R3 for full digitally controlled push button cruise with decelerate, accelerate and resume features. The other problem is you need a vacuum tank to store the vacuum to pull the servo and space is at a premium on the R3. the CSS unit, with sufficient vacuum, will hold your speed within 1/2mph up hill and down hill, something that no throttle lock, cramp buster or Throttlemeister will ever do.
I've considered offering a kit on my website but sourcing the componentry would be a hassle and it's a pretty complicated installation as well.
