It's a throttle tension adjuster.
You can set it to hold the throttle like a cruise control. If set right you can open and shut the throttle with differing resistance to the point it's stiff and holds the speed without having to grip the throttle all the time.
Over-tightening it could prevent you from closing the throttle.
There are different types of levers that are sold aftermarket to extend this to make it easier to use. One style retaps the threads so it makes more of an adjust for the half turn space available.

I use it all the time on the open highway, it takes the strain off your wrist holding the throttle open for hours at a time. Tighten it just enough to hold throttle tension, and the throttle can still be easily opened and closed.

I use it all the time , especially on my rigid bike.
it keeps the bumps from causing erratic throttle movement at slow speed.
smooth's out the throttle at hiway speed ....no throttle cramps..
trick is to be smarter than the throttle friction brake
