Brought my DRZ400 to life!
The JD Jet kit is a must. Bought it for my DRZ400 and it unleashed the beast in her! I set it up so it would preform at higher altitude. (Bought the bike on the east coast at 3000 ft, took it out west with me.) This thing now rips! Took it up to almost 13,000ft on the Peak 9 summer road in Breckenridge! Didn't skip a beat and still had tons of power and torque which it didn't have stock.

High recommend as one of the first mods to a stock bike.

The JD jet kit has made my crf150r a mini monster with much better lower end torque and helped get rid of the bike bogging out.

What size jets does this kit include? Is it just the stock set or are there options for re jetting?
Robert M on Sep 25, 2016
BEST ANSWER: The kit will include the stock jet sizes and in most kits (depends on the machine) it will usually include one or two jets close to the stock size for re jetting.
Does this kit come with leak Jets and what sizes if it does. I would be purchasing it for a 01 wr250f?
Aaron M on Feb 24, 2018
BEST ANSWER: The kit for my 07 yz250f did come with a new leak jet size 45. The kit i got for my 07 CRF450R did not come with a new leak jet.
Does Rocky offer the JD jet kit for a 2017 Beta Xtrainer?
A shopper on Jul 24, 2017
BEST ANSWER: Unfortunately, we are not carrying the JD Jetting kits for this machine. However, I will send your suggestion to our purchasing department for consideration.
I have an aftermarket pipe, how do I account for that in the kit?
kelly C on Feb 6, 2017
BEST ANSWER: There are multiple variations allowed with the kit. Follow the instructions for altitude etc., they should be close. You might have to do some testing to fine tune your jetting but it won't take long. I have an aftermarket pipe and am at altitude (Wyoming). I followed the instructions but had to fine tune (lean out) my jetting as the recommended settings were a little rich.
Will this work with a keihin carburetor on my 2004 YZ250?
A shopper on Feb 23, 2017
BEST ANSWER: I can say for a fact that it will work on almost all the CR series carburetors that are found on all of the 450s of that time frame (some mods need to be completed on the California carbs). It will possibly work on yours as well, but it is a smaller carb. I would suspect that the jet selection in the 450 kit would be a bit on the large size, and I'd be particularly concerned about the needle profiles contained. They may also fit, but may be too long, or not have the right shape. That is assuming that you are talking about the YZF250 (4 stroke). If you actually have a YZ 250 (2 stroke), that is a totally different carb than the kit you are referring to. I bought one for a 2007 CRF450X from Rocky Mountain ATV/MC, which is why this question was directed to me. In short, I would say NO. This is not the right kit for you. I would get on line, and look up JDJetting dot com, tech at jdjetting dot com, or call them at the number on their website. (I am not allowed to include email addys. or phone #s in this reply) They will direct you to the correct product from their line, which is most likely also available from Rocky Mountain ATV/MC. I hope this helps. Good Luck!
Hey folks I have a 2016 yz 250x has anybody tried a Lectron carb on the same or similar bike? I've read cool stuff online I'm tempted to snag one. This is my first bike so i'm a total amateur, I hear they are really easy to adjust which is half the reason I wanna get one. Would people recommend this over getting a JD jet kit?

BEST ANSWER: I purchased a lectron when I first started riding several years ago and still have it on my husqvarna wr250. But honestly a have a regular carb on my 300xc and once its jetted I leave it from spring to fall once you tare into a carb a few times you'll catch on quick. The only reason I'd say a lectron would be nice is if you live were your ride from sea level to 10000ft in one day it would shine then. That's just my opinion tho.
Hanging idle issue. I have an 2018 KTM 300 XC-W with a JD kit installed. Red needle, 3rd clip position, 420 main, 1 1/2 turns out on the air screw. VForce Reed kit installed and FMF turbine core 2 pipe. The issue I'm having is with a hanging idle. Any thoughts? I'm thinking I may need to richen up the mixture a bit ( possibly move the clip position down one ) and retry.
ANDRE M on Mar 31, 2018
BEST ANSWER: Your issue is likely the internal gasket on the Mikuni carb. look this up on KTM talk, It is a jet block gasket failure. JD jetting sells a kit to fix the issue.
What difference is there with buying this kit vs. just jetting my bike myself? Are the needles that much better than oem? 06 Yz250.
RANDY H on Sep 11, 2017
BEST ANSWER: I used it on a 07 Honda crf450r and it popped. After contacting the company, they offered no more guidance than was listed in the instructions. I took it to a Honda mechanic and he jetted it. It ran pretty good with the kit in, but it popped and it annoyed me. The needle was not much different than stock.
I have a 01 KTM 125sx. How much power increase can I expect from this kit?
cris n on Mar 21, 2017
BEST ANSWER: I wouldn't expect a power increase (although it can give you that) - what you're looking for with a jet kit is to make the engine respond correctly to all (most) throttle positions at any RPM range. To say it another way, you typically won't be able to discern the power difference by riding, but it should run better if done correctly.
How to I get another set of instructions? I lost the ones that came with the jet kit. Thank you.
John D on Jul 28, 2019
BEST ANSWER: It’s actually easier to email their tech they have incredible customer service and will email you back the specs
What's included in the box?
Levi S on Oct 23, 2017
BEST ANSWER: JD kit has two needles (hot and cold weather), one needle clip and 5 main jets, and instructions, problem list and suggestions..

FMF Power Core IV S/A Silencer
BEST ANSWER: Oops I found the TRX! But still, this is not the correct one. The one you need is FMF number 41269. The Rocky Mountains number is 1047000081. Hope this helps!
I’ve tried to get info from JD about temperature settings. They told me that they are set or referenced at 50 to 70°. I wrote back and haven’t heard anything. I live in Wyoming, my riding temperatures can go from 10 to 90 within the year. Any info?
Paul F on Feb 28, 2019
BEST ANSWER: Another factor to consider is elevation. What is your elevation there?

The main jet will survive a huge swing in temps as will the pilot jet:::: But the fuel screw (air fuel mixture) will need adjusting along those big swings.
I can’t see what bike you are putting all of this on but if they offer an external adjustable air screw then I would also get that so it’s easier to adjust each day.
I hope this helps you some.
I have a 95 yz250 and ride at 8000 feet elevation and do a lot of free riding and jumps and my bike is running really rich and fouls plugs what kit do I need?
Earl B on Feb 21, 2018
BEST ANSWER: If you buy the JD kit then you'll get all the parts you need (pilot jet, main jets, needles, etc) and instructions to help get you in the right ballpark in terms of jetting for your altitude and riding conditions. Then if you're still having issues you'll have access to their support to help you adjust it from there. I can't speak for your YZ250 specifically, but I've used these kits in a few bikes with good success just using their recommended settings at whatever altitude I'm at (between 5-12k).
Can I get replacement directions?
robert l on Feb 11, 2018
BEST ANSWER: JD jet kits usually have instructions with them. If they do not, just go to their website and download a .pdf. If you need to, give them a call, their customer service is awesome.
I have already purchesed a kit but need a replacment needle due to dirt getting in my carb and damaging it, where can i get one?
konner p on Jan 22, 2018
BEST ANSWER: I would contact JD Jetting. We do not sell just the needle for this kit.
will the crf 150r kit work for my crf 150f?
A shopper on May 18, 2020
BEST ANSWER: It will not.
How do I get to the needle on a 4 stroke carb?
Jackson I on May 6, 2020
BEST ANSWER: You can access it by taking the bottom of the carb off it’s super easy to get to and change
Do you have a kit for 150xc w Ktm 2018?
Brandon P on Mar 31, 2020
