I installed Jd jett kit in my 07 yz250f after riding a buddy's bike that he had just bought with a jet kit and exhaust. I used the exact setting came with the kit and it seems to be great right now 50 degree weather. Starts on one kick without any problems and the throttle response is so much nicer now, no sluggish throttle when you just snap it, it goes. Really impressed with how this kit woke my bike upRead All Reviews
