I am having a hard time with thumb fatigue on the 2006 450R. Has anyone tried one of these springs in theirs yet?

Does it work?

I have lookedi into other springs for the yfz and have yet to find one that is made for an fcr and has a lighter pull. The spring on the 450r fcr is not the same as the YFZ. As for the 06 450 the thumb throttle has to go. Dusty uses a different throttle and lever and has been happy with it.

Put a 04 05 thumb throttle on it and your thumb will be happy !!

i am having the same problem. my friend said he ordered this spring for his yfz so i will see how much it helped. i am really wanting to do something about it because i doubt i will last a whole moto with it like this. i never got tired riding my 04 but after acouple minutes of hard riding my thumb feels like its going to fall off.

Any issues with eliminating the throttle position wires on the 2006?

I have that exact spring in my yfz 39mm fcr carb, and it worked wonders for me.

Hey Bart
I race w/ 2 people who have cut their springs then stretched them back to stock length and nade it much easier, just like the 250Rs flat slides. Don''t try any more than 1/4" or it made stick a little until the fuel gets in there and lubes the slide.

Big difference

Twist throttle. Since I injured my thumb using a thumb throttle back when I bought my 00 400ex and put on a twist, they have been on my quads since. You won't even think twice about it once you get used to it.
