thinking outside the box but maybe someone could cut down a shim to slide over bars and maybe hold with a couple small set screws then put throttle on?

you mean just like the shims you get for the triumph p clamps?
drill a couple small set screw holes in each?

well to be honest that was my first thought but then after thinking more i think a one peice sleeve would be the better choice if i had my choice and two small set screws one at each end.

that would probably be a better idea.
i dig this throttle. it's pretty short,length wise and it looks perfect on the bars.
when i picked it up,i just assumed it was 7/8's...wrong.

Yeah, the throttle isn't held on it's whole length, it's only held to the bars where the clamp is, so no real need for a full sleeve.

If you like short grip area throttles, anything can be shortened with a hack saw. ^^

the plastic throttle tube should be the same length as the grip so I would want to "shim" the dia. whole length. If you just shimed the clamp area, the throttle tube will be unsupported and wobbly, maybe even get cocked and stuck while at wide open :(
A pc of 1" dia tube w/ a .062" (1/16") wall thickness should do the trick to slide over the old bars and be secured w/ set screws or maybe even epoxy.
Or cut slug and weld on a length of 1" bar.

Same thing that the riders did with the internal throttle bars. A full length pipe, pressed on to the smaller diameter of the bar, and then they could use a regular snap throttle. I restore them every time I find one, back to the internal style.

Cut the bars and weld a 1" piece on. I do that for 7/8 clip ons to make 1" handlebars.but new 7/8 throttle cam be had for cheap.
slug in a piece of 1" bar just short of the throttle length...

Looks sorta like a Barnett throttle, not particularly unique. If you like the short grip area, there's always the option of finding a similar 7/8" throttle and shortening the sleeve. Seems like it would be a lot less work.

That throttle was made in Japan and sold in the seventies and is a copy of the common british style throttles. It came in "Superior" packaging with a left side grip. The rubber grips are 1" inner diameter on the clutch side and 1-1/8" on the throttle side.
A piece of 1" handlebar tubing will slide over your 7/8" bars with a little file and sandpaper work. Use JB Weld to hold that sleeve in place. When looking for a 1" handlebar to cut up for the donor try to find "seamless" tubing. The word seamless means that the tubing is actually without a welding seam on the inside. Tubing is either folded into a round shape and then welded or drawn over a mandrel to create the round shape. If you cannot find seamless tubing you have to file down the weld on the inside. Hope this helps.
