Awesome!

Comments On Mar 17, 2014:Easy to install and works great. Followed the directions for the high altitude set up (we live at 5000') and she runs like a champ...much better than the factory set up. No bog, no high idle, no cut out on rapid throttle application. BUY THIS KIT! You won't be disappointed.

boggy throttle response

Comments On Mar 01, 2014: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 up

Easy to install

Comments On Feb 09, 2014:I have friends that have told me to get this kit. Seeing as we live around 4000ft and then go riding upwards of 6000ft+ in the mountains, it seemed logical to get this. I haven't tested it yet, but I've had friends that love this simple kit. The instructions that it came with were easy to follow. AND I didn't have to remove the carb! Easy to install, and a quick fix to major problems of bogging!

Works great

Comments On Dec 26, 2013:I installed this mainly for the quality of the needle but the jetting was spot on as well. Idles great and the throttle response is outstanding. I can lug along single track without any loading up and not worry about the slight temp changes. Overall, very happy with the product and glad I installed it right away.

It takes the guess work out.

Comments On Oct 19, 2013:If you have jetted a Honda 250X, you know how much of a pain it is. With the JD Kit you can get it jetted right the first try. I have used JD Kits on all of my bikes and they have always run great. Great throttle response, no bog and no more overheating.
