will fit on my moto i just about lost it friday night.
the way i ride it seems that i get my index finger stuck behind the thumb throttle not a good thing on the track.
it has happin 3 times so far . so if you know what will fit let me know (this is the only thing bad about the quad)

 

I believe the twist from the c'dale bikes will work. My hands float too much to. I have to use grips with a flange on the inside. :confused

 

I saw a guy running a 400ex thumb throttle on his....but I don't think it was opening up the throttle the entire way. Best thing, would be to contact the shops that are sponsoring racers. They've made some mods to the stock setups, and might be able to shed some light on the matter. Have you tried running the thumb throttle at different angles yet? It took me awhile to find a comfortable position with the thumb and the front brake lever....I like to run my lever pretty far down, and the throttle was always in the way. I've found a decent position finally.

 

thats the same way i run mine i was thinking of moding a 400ex throttle to see if it will work
