fcr stiffness

I have a quad with a yzf400 motor and I use a thum throttle and after 2 laps around the track, my thumg is so sore that it actually swells, any tips to make it easier?

Sell it.

And get what?

Can't you put a twist throttle on it :cry:

Bro my 250r is the same why. Just deal with it. Actuly go put glue on the slide of your carb and let it set up a bit and you will know how mine is.

Well yea I can put a twist on it but prefer the thumb cause ive only ridden quads my whole life. Im just askin if theres any mods that can be done caus enot even my edelbrock is this stiff! Can you grease the slide on the sides?
