Jd jet kit
Great product and awesome company I called the manufacturer before buying product to be certain it would work on my snowbike. The jetting was spot on and comes with a jetting chart to adjust for different elevations

WOKE UP THE BIG OL DR 650
Carb was bone stock on the Dr 650, Ran just good enough to be rideable. Was not dirty fuel was fine. Not much throttle response. What a night and day difference. Totally different bike, instant response. Pulls hard all though the RPM range. Runs actually cooler. Worth the price.

ANYONE CONSIDERING THIS FOR THE DR 650, YOU WILL NOT BE DISAPPOINTED!

Hoping to return
Not one setting helped me out with the low-mid range problem on my 300xc. I was reluctant to purchase the kit due to cost, then I told myself if the needles work then it would be worth it. I am not using either needle nor the 3 or 4 jets they threw in with it. I am actually pretty pissed off about it now.

Suzuki DR 650 SE WOW! What a Difference!
My DR 650 had the usual issues with carburation. It was running lean, surging when trying to maintain a steady speed and terrible throttle response. I spent the little bit extra and bought this kit. I live in Arkansas but I love to run out to the Rockies and hit the high passes, so I can use the additional needle and jets. This is only my second carburator job but the instructions were actually very good. I followed the instructions and set up the carb as recommended. It cranked right up and ran like a totally different machine. It's now a bit cold natured where it wasn't before. I start with the choke and open it up after 30 seconds now. The bike has much more power at low rpm. I can shift into 5th about 10 mph sooner now. I used to have to get over 50 before I could shift into high. I hit the interstate on-ramp and cranked it open. That's when I got this big grin on my face. WOW! What a difference! It felt like I just gained about 10 horsepower. The throttle response is immediate and strong all the way up the power band. On the way to work this morning I got it up to 95 in a short distance and I know she's got more. I just don't have a death wish with my 50/50 tires. I highly recommend this kit. The needles are the big difference maker. They are made to improve low end performance and they truly deliver.
This kit is worth the extra bucks. It's not an easy job to do yourself, despite the good instructions. Removing the screws from my carb required grabbing them from the side with vice grips. You have to be extremely careful to keep track of all the small parts and know where they belong. I recommend you buy a gasket kit and replace the bowl gasket and o-rings. They live in ethanol and no material can hold up to that for a long time. They get flat and brittle. Drilling out the plug for the air/fuel screw is another opportunity to fail. Take your time and don't drill into the screw.
There is a good thread on the ADVRIDERS forum for my carb that was very helpful. It had good photos and gave me more confidence.
Get this kit and unleash the beast that is hiding behind those pitiful stock parts!

Jd jet kit for DRZ400S
My DRZ had carburetor issues and I didn’t want to do a bunch of trial and error and had read good things about the JD jet kit so tried it out. The instructions are very detailed and easy to follow to address whatever mods you have done to the bike. First time around the jetting was spot on and runs 100% better. The kit was a bit expensive but I also didn’t have to waste time trying out different jets and adjustments.

I installed this kit before leaving on the Trans America Trail in June. Super easy to install and no guess work. I jetted for about 1000 feet and it was fine all across the country. Even at 14,000 feet I couldn’t feel power loss. I know that’s not normal and JD doesn’t claim it’ll be that way, but I was super happy! Guess my bike is special! But I carried the different jets along just in case. Would recommend this kit. 6500 miles, no problems.

Hi, so these come already set for the altitude that I need or someone is gonna ask me after ordering?
Victor C on Feb 5, 2018
BEST ANSWER: They (depending on which kit) usually come with a couple different tapered needles and a few different size jets so that you may jet it to your riding altitude (the chart is included in the instructions) so no, no one will ask you what altitude you’re riding at while ordering.

Doug N on Feb 17, 2018
BEST ANSWER: The 25 and 155 jets are included.

What is the difference between the "Non-CA" kit and the "CA kit"?

Is this kit suitable for a 450 exc fitted with a wiseco 12.5:1 piston?
Michael S on Apr 17, 2018

A shopper on Apr 6, 2018
BEST ANSWER: It comes with 4 main jets (155,158,160,165) a pilot jet(42) and 2 needles(red,blue). Instructions are very good as to which to use and when.
