Ok, I found out that there is a correlation between the throttle return cable and the thumb screw. After continually adjusting the cable I could get different effects on the thumbscrew. I think I'm close but not quite right.
Obviously I had to do the left, center, right test to make sure the throttle snaps back but even after that I could get different effects on the thumbscrew.
Tis a very weird relationship me thinks...wish a tech could eloborate on the thumbscrew because the service manual doesn't even address it.

Most of us over the hill old-timers like it just fine. For you who don't think it is useful on mountain or country roads, well it is more useful there than cruise control. I never have mine completely off.

Might have to revisit his product again, mine was from another company and no matter how tight is was , as soon as I got going the vibration would release the hold on the throttle so my wrist had no relief. Much less expensive that cruise control.

If I tighten mine just enough that the throttle won't back off by itself I can cruise along. If I want to shut down the throttle I don't mess with the screw. I just grab the grip and twist the throttle off. It just adds enough friction so the throttle will stay where I put it, but I can still easily move the throttle. It's nice for the highway.
If you think the current implementation is a pain, be glad you weren't riding in the shovelhead/ironhead days. It was a smaller metal thumbscrew that was even more difficult to set.
That said, if adjusted correctly, you should be able to just slide your thumb down, give it a half turn, and it will provide enough drag to hold the throttle position (but not so much that you can't manually override it and throttle down if need be).

Get a throttle rocker, or Cramp buster, it was the first thing I bought and I will never go back.
