Loose throttle sleeve?

[Rough-but-slow]

A big problem with R3 throttles is that the last 3/4" or so actually gives little or NO support to the sleeve - mine has all sorts of additional stuff in so it does not waggle.

What sort of stuff?

Maybe it was the hand gripping the grip that caused this,when you fix it try not to hold the dam thing so hard.

Well customs bars with a 7/8" section let into the section where the throttle tube rotates - with precise igus slider bearings in the throttle tube. The throttle tube was worn a bit. I have zero waggle now. On standard bars - you need a short piece of bearing material that fills the reduced section of bar to the inside of the throttle tube - and you may need to teflon shim where the cable guides are.
