Rizoma throttle tube slipping.

[mookieo2]

not sure if this should go into Tech.

My Rizoma grip is slipping on the throttle tube. It started out when I would give it full throttle it would spin after the throttle was all the way open. (Thanks to a few track days and the bike not being fast enough) A 500 mile ride yesterday and it got progressively worse. I would go to give it throttle out of a turn and sometimes I would have to "walk up the grip" to get more to roll on.  Almost home last night and moving at a good pace off the exit ramp, leaned over pretty good and It wouldn`t grab. It spun and I could hardly get any throttle to get out of the turn.

I was thinking about taking a socket or some kind of seal driver and seeing if I could separate the grip and throttle tube and maybe epoxy them back together,and add a set screw to it like the clutch side or something like that. Has anyone had this problem?

Several have had this problem.
I don't have Rizoma grips, but I've seen this issue discussed.
Guys with FHE will probably chime in.

If it's the rubbery bit... bust out with some crazy glue.  I had to do that to some more normal grips on a borrowed bike.  The throttle would slowly close due to the tesion of the cable pulling on the tube, with the grip was no sufficiently secured to.

Thank guys. I  will try to epoxy them. It is defineately not the rubber grip. I was thinking about going back to stock anyway. I scraped up the left one during a get off last season so it annoys me and I don`t feal like buying a new set. Anyone want a throttle side in gold with a bar end?

Had it on mine.  JB Weld fixed it in a jiffy.

Just a quick question, what happens when you need to take these things off? The rubber part would wear just like any other grip, correct?

you can buy replacement rubber "grips" for the aluminum sleeve.  They're relatively cheap.

I had trouble with teh cams on mine, so rather than continually messing with it, I separated the plastic throttle tube from the aluminum sleeve with a long, thin screwdriver, and then I glued the Rizoma sleeve onto the Ducati throttle -- I had to sand down the throttle then I pounded it in and used Gorilla glue -- that was last year (at least) with no slippage...

I ended up doing this too :p  Worked out great
