Handlebar accelerator grip sticking.

Everything was very straight forward since the wires were already on the outside of the bars. All I needed to do was unbolt things, and bolt them back into place with the new bars.
The old bars were the mini ape hangers, so I do have some excess in my cables, but I will worry about that later. It is not enough to bind, or to keep it from turning smoothly.
The problem I am having is that the accelerator grip does not seem to return to its normal position smoothly. If I let up on it, it sticks for a few seconds, before it returns to idle slowly.
The more I rode it, it seemed to get better. Which may mean I am just jumping the gun on posting this. It could be that if I take it out a few more times, it will work itself out, but who knows.
I did grease the bar before I put on that grip. I am assuming this is correct, since the bar I took off was greased in this area. I used PolyLube 1000, which is bearing grease formulated for bicycles. It is what I had easily at hand, and I assumed it was close enough to whatever was recommended.

Would also assure sufficient slack in throttle cable adjustments, at both ends on each cable, and no binding anywhere. Should be virtually zero drag when inner cable is being pulled either way through its sheath.
Would lightly grease ferrule connections at both ends on each cable.
Also check linkage and action at carb for any binding. Okay to lightly oil.
Good Luck!

I always grease under the throttle on the handlebar. I just do. I don't know why but it seems like a good idea....
While the earlier FSM (73Z1-76KZ900) is silent about it, the FSM for 77-79 KZ1000 does indeed call for greasing the handlebar under the throttle sleeve.
Chilton's Z1 manual doesn't mention lubing the handlebar area, nor does the original Z1 owner's manual.
The early throttle sleeves are some plastic composition. Perhaps later models changed to a metal sleeve. Uncertain whether this change would have made a difference, or if petroleum based lube might possibly be harmful to the plastic.
The objective is a freely rotating throttle sleeve with minimal friction between it and the handlebar. The throttle should snap closed when released, via pull from the strong return spring on the carb assembly.
Good Luck!

The throttle should be lubed.
From the looks of the pic, loosen the throttle cable locknuts up at the switch housing & rotate them so they aren't binding - see if that helps. As mentioned make sure the throttle wasn't rubbing the bar end. JMK.

... From the looks of the pic, the first thing I'd do is loosen the throttle cable locknuts up at the switch housing & rotate them so they aren't binding....
Again looking at the pic, I concur with JMK. It does appear the cable elbows at the switch housing are preventing a smooth gradually routed turn for the cable.
Presumably, there's a locknut holding each elbow in position aganst the switch housing. Could experiment by loosening both lock nuts and allowing the elbows to assume their "natural" position (probably pointing straighter out towards the front), and leave the locknut loose while opening the throttle and allowing it to snap back closed on its own. This "natural" positioning may resolve the problem, and if so the locknuts may be re-tightened in the non-binding position.
And as already suggested, assure the handlebar itself isn't protruding beyond end of the throttle sleeve whereby the hand grip rubs against end of the handlebar.
Good Luck!

i will try tinkering with both things, and see what my results are.
