Anyone use a JD Jetting kit??

I recently bought a 2002 CR250R and I just re-jetted with a jd jetting kit.The best money I have spent!! It greatly improved throttle response.I would highly reccomend this kit to all. :)

Yes I put one in my bike last year as soon as I got it. The stock jetting was pretty far off, so it definitely got me in the ballpark quick. I still need to play around a bit more, but it was pretty good except needing on size leaner pilot than what JD supplied.

JD "James Dean" used to post here a lot... found more money elsewhere for his kit? Here's one from 2000: http://www.dirtrider.net/forums3/showpost.php?p=22198&postcount=10
