great product
bought this kit for my 2014 klx 250s, got this in combination with a fmf silencer, header and twin air filter. it helped wake the bike up a good amount. the instructions were easy enough to follow. getting to the carb on that particular bike was a pain in the but.

Get a JD jet kit
limited jets and needles. may work great for sea level, but not if you live higher. My DR 650 ran poor with this kit. Put a JD on and it worked perfect. Spend the money on JD if you have a DR650!

I used these for years and they work
I've used these for years and they work. Installation is fairly straight forward but their instructions are poor in my opinion. The included photo on my instructions was just a waste of time and they include more parts than you need, which has to increase the cost. The plastic container it all comes in also seems like wasted expense. When I called to try and figure out what the horrible photo was supposed to be showing me, they were of no help. That said, they are cheaper than some jet kits. They could save some money on packaging and bring their instructions into this millennium.

Jetting trx250ex
This jet kit was amazing ordered it to up the throttle response after putting a exhaust on my xc 2014 trx250ex..... It runs amazing now! It takes off quicker.... The kit woke the quad up through out the whole PowerBan. I would definitely recommend this product..... It was also fairly easy to install other than the carb needle which I ended up not installing. I give it a 5 star rating.

After getting the floats set at the right height my warrior runs great with this kit. I like the variety of main jets the kit came with. Instructions are good except they don't explain where to put the washer, I put it under the e clip on the jet needle. Works awesome

All the right parts
Kit came with everything I needed and the directions were clear and easy to read.

On my first test drive afterward what stood out the most was the 45 to 55 mph surges went away. The ride feels more comfortable. The throttle response is better and wider, I can go slower a little slower which out downshifting but more over I can pull out of it easier than before.

This kit is not as complete as the JD jet kit it didn't come with the variety of Jet's I wanted and it didn't have new bowl screws I swapped it for the Jd kit due to this

BEST ANSWER: Everything should be included for the carburetor you are ordering the dyno jet kit for, very easy to install, as well as step by step instructions
does this come with the D shaped bit for the fuel/air screw?
robert d on Oct 15, 2017
BEST ANSWER: If the jet kit installation requires that tool to adjust the air/fuel mixture screw for your particular model, then it will be included in the kit. Kits that do not require that tool will not have it included.
Is the image of the jet kit the same that i will recieve?
Ronaldo M on Nov 15, 2016
BEST ANSWER: Yes, and even more jets than shown so you can adjust for altitude, temp etc. Even comes with a drill bit and wood screw to use in case the air screw is blocked by an epa plug. Lets you drill into plug, thread with wood screw and pull plug with pliers allowing you to change jet. It all comes in a nice plastic compartmentalized case with hinged lid. I boujght kit 2152.

How much more fuel are you using after the installation of the DynoJet then from before the installation?
Shane M on Feb 1, 2017
BEST ANSWER: From my experience stock jetting is notoriously lean, heating correctly with dynojet or similar will use impact fuel consumption slightly, however nothing that will be dramatically noticed. Plus you will have the advantage of better response and by removing the lean condition you will run the motor cooler.

How many jets come with the kit? What is required to install this kit in my quad and are other enough jets for a two stage?
TJ F on Aug 6, 2017

Is the dyno jet kit the same as moose racing jet kit?
A shopper on Aug 17, 2016
BEST ANSWER: The kit is not the same. dyno jet is a manufacture of the jets included in the kit and differ from manufacture jets which are what the moose jets are most likely based off of. The dyno jet kit comes with a special tapered needle to work with their jets and includes instructions.

Grady H on Nov 20, 2017
