Non Graunchy Throttle Pipe

Discovered something new to get rid of slip-stick motion of the throttle pipe when under extreme pressure. I call the feel of the slip-stick motion 'graunchy'.

Oil helps, but sometimes the graunchy returns. Had greases produce graunchy right away.

Baso makes a pricy propane and natural gas valve grease. You know, to smooth turn and seal the taper-seat valves on grand ma's old gas stove.

It's a thick moly paste. Too thick for throttle pipes, but when you smear it on the bars before sliding the throttle on, trickle on some oil (I used synthetic ATF), then swirl that up to a thinner paste with a finger. Voila! A perfect lube to smoothly float the throttle pipe with zero graunchiness... if you care about such details.

Easy way to get very smooth throttle action is to fit a Hebo bearing kit:

In conjunction with an Xblok slow to ultra fast tube, these mean greatly improved throttle action, and will fit most bikes.

Yes. I had the bearing in the Raga throttle pipe. Replaced the throttle complete and did not want to transfer the bearing. Never had a problem with plastic-on-bar end as long as it was lubed well. Saw the ramp on the Xblock and thought it interesting. Since the former Raga throttle had a ramp hand made in aluminum epoxy, if the throttle response proves a bit slow with the standard white pipe I might go for the Xblock. I recall someone made a machined aluminum slip-over ramp at one time.

Xblok throttle tubes are something that work so well, you would never want to use a standard one again after using one. I would guess all the factory riders are using something very similar
