Lubricant for VM28 carbs was created by sf4t7
At the risk of starting yet another "oil discussion" -
I'm ready to assemble my VM28's after a thorough cleaning, what is a good lubricant for the moving parts and pivot points?

I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.

A light wipe of Frog Lube grease on the ball & cup joints & disassembled rotating shafts, one drop of Frog Lube liquid on the tip of a toothpick for any assembled ball & cup joints, particularly the two ball & cup joints inside the slide. Maximum two drops of Frog Lube liquid on any other moving parts (shafts mostly) still assembled. A damp wipe of WD-40 on the slide & slide bore, then polish dry with a lint-free cloth for final clean, dry insertion.

If it helps? I do multitudes of carb 4-cyl banks. If the bronze (2) are in decent shape and the holder isn't warped, just slide it thru to verify first, any oiling isn't a make-up for warpage. There are felt o-rings that keep the grit out. No reasoning to put any emollient to "grab" grit from the surroundings in the bracket 2 bushings, like hardrock mentioned, dry is just fine. If You are working on the 72-75 carbs with multiple joints use a silicone grease like Dow Corning High Vacuum grease. And walk a bit down the threads of adjusters too, keeps everything happily adjustable in the future.

Actually to verify this conclusion as to oil or not, pull Your shaft out the bracket, You won't find any lubricant. Just dried out brown felts perhaps but you won't even find any semblance of any lube as originally equipped.

One has to equate this same scenario as to the consensus that to lube up the handlebar for their RH throttle flute makes it better for response and quick return. It's a fallacy been often touted and often practiced but always a bad idea. All one does is create a bed for a grit compound , the stuff you would want to finish lap your valves with. I've seen plenty of this misconception/construed over the years.

thanks for your answers.
Oops, when I assembled the bars, grips, and levers I used a little lube under the throttle sleeve. But the Oury grips are closed on the ends so maybe it won't be so bad.
edit: On second thought it's winter I have time to clean the lube off from under the sleeve.

I use waterproof grease in the bronze bushings for the throttle shaft. For the choke actuation shaft, I use dry Teflon spray lube, after the shaft is installed. On the slide ball joints, I use this dry lube stuff intended for bicycle chains. It's thicker than the dry Teflon stuff, so it has more staying power.

I'm in the process of rebuilding the VM28's for my 78 z1r and noticed the felt o-rings on either side of the control shaft are all but gone. There isn't a part number but I imagine someone has found a source for replacing them.
