2017 250sx

My 250 was loading terribly- most notably on the starting gate. Plus I couldnt stand the way the bike sounded like a 1983 CR 500 on decel. I installed this JD Kit and it was an amazing difference with crispness and response as well as fixing the weird decel sounds. Just purchased for my 18 125sx and I'm about to install today. Psyched.

Clarke gas tank

I put my Clarke tank on fix right on looks good. Now I can ride a long way now. It sucks when you run out of fuel.

Good product

The instructions explained exactly what needle and jet to use for my specific elevation of riding. I’ve used jd jet kits on my other bikes and they work great. The only downfall is it didn’t specify what jet/needle combo to use with an aftermarket pipe.

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.

A: The kits offer a fairly wide array of jets and needles. I cannot say whether or not the jets supplied would cover your unique needs. I would suggest reaching out to the manufacturer's tech support prior to your purchase.

A: This kit is built for the tolerances of stock, since its bored out you will need to call the manufacturer or your local mechanic to determine which jets will work for your bike.

A: That will depend on the year/make/model of bike, but this jet kit will come with a range of main jets, pilot jets and needle jets with settings from sea level to 12,000 feet elevation.

Q: Wife has a 2017 crf150r with a twitchy/unstable throttle at times in low gear/low rpm situations. Looking for an option to smooth that out for her. Would this accomplish that?

A: Other than it being a small bore race bike, I am not sure why the throttle would be unstable. Jetting would not likely help. You would be better served by running taller gears that would lessen the torque, and maybe adjusting the clutch lever so that it has more free play.

A: This jet kit is for OEM-ish bikes. I personally feel like having a big bore kit on the bike, these jets would not be big enough.
