So quick and easy!!

I recently uncorked my WR250 and ran into some stumbling and blogging issues as well as a lack of quick torque. I bought the JD kit, and man has it turned this into a new bike. I can now easily lift the bike over rough terrain and logs with confidence! The instructions are very thorough and it makes it super easy. Comes with plenty of jetting options to make the perfect tune.

Big improvement!

Put this on my 2006 crf250r made a positive improvement over all. Comes with two needles main jets and two O-rings. Currently running red needle 5th clip with 185 main and the thicker O-ring of the two. Took that dreaded off idle bog away for the most part. Overall highly suggest this to anyone looking to tune up their carb with performance in mind.

My DRZ runs better after I installed the kit.

Jetting kits cost a lot for what they give you but they are a bargain for what they accomplish. Removing and reinstalling the carburetor on a DRZ 400 is kind of a pain and it is better to spend your money on a JD kit, follow the instructions one time and have a great running bike than to figure out the jetting variables yourself.

Works great 32.5 pilot 3rd blue needle and I believe 450 main works great in Michigan

Didn't work

bike wouldn't run with 30 pilot, had to put on choke. stay with stock settings on 2018 KTM 300 XCW and follow chart and the bike ran well.

Best Mod for a DRZ

As most DRZ 400 folks will tell you, the 3x3 air box mod is needed to get the full potential out of the engine. There are other kits out there but this is the one with the clearest directions and the widest options for altitude and exhaust types. The difference in power and throttle response is huge. Very happy with my purchase, it came fast and was easy to install

A: Sounds like you could be running a bit too fat on the pilot jet, but you should have a professional technician in your area assist you. They would have a better idea of proper jetting for your location.

A: The jet kits come with a chart as to what jet sizes you will need with the elevation and modifications. If you want specifics you would have to call JDjetting.
