Recommended Jetting Kit

1 post in this topic

Hi, I'm getting a new top end on my '02 WR426, and I'm boring it out to 440 at the same time. I'm going to need to re-jet - is this what I want? http://shop.thumpertalk.com/ProductDetails.asp?ProductCode=int_jdjetting_jetkit&Click=7996

I'm going to buy the Thumb-adjustable fuel screw as well.

Secondly, I need to buy stiffer fork springs and a stiffer shock spring. Should I get these from TT as well?
