Dynojet Jet Kit

Upon receiving this kit i noticed that none of the jets were manufactured as the OEM jets. Even the “stock” sized jet was
noticeably bigger, it also required an adapter to fit into the bowl. I decided not to use this kit and bought all OE jets.

2000 Honda 400ex with bolt ons.

total uncork of the 2020 XR650L..ordered the dyno kit..read the instructions,called mostly for snorkel removed+foam filter...well i did much more then that,port/polished header/modified muffler(built my own baffle/spark arrestor/3/4" to 13/8" opening)removed snorkle,plus 2" by 3/4" opening in side panel.so i called dynoport,explained all i did, my area.he crunched the #'s and gave me a ball park,which was same as directions..today since we had nice weather..i took her out for a few laps around the property...WOW..big difference then the STOCK SLUG...throttle response great,crisp,clean running...you twist that barrel ,the give me a second(bog)stock version is OUT of HERE,bye..bye.....Dyno Jet kit well worth the money/time.wake that red pig up today.....

Installed on my new DRZ400SM, works great. What made me second guess myself with the carb out was that the forums popular opinion (with JD kits) called for a higher jet than what the DJ kit calls for, STICK WITH THE INSTRUCTIONS! It took me a long bit of searching to find that the company's jet sizes are different. I thought there was a standard of some sort but just follow the directions on whichever kit you get, or be prepared to pull it off and swap jets frequently. The kit came with two drill bits and a screw to pull the brass cap off of the fuel mixture screw, as well as a lot of extra jets for "future mods" although I can't speak from experience.

I installed this on a 2008 XR650L. Bone stock with a Uni air filter and the snorkel still in-place. The kit says to leave the pilot stock at a 50, but at 2500’ I had to swap in a 52. This combo and a little fuel screw tweaking made it run super smooth. You could do the Dave’s Mods, but the Dynojet needle makes all the difference.

Can’t believe the difference it made on my trx400x. Highly recommend!!!

Rejected my 07 Teryx, starts so easy now!! Runs awesome and can’t wait to try it up at higher elevations! Once you get to the carbs, super easy install.

I had issues with my 660 raptor. Would not stay consistent with idle or mid range. I thought I had it fixed on my own with adjusting it. Still issues. After weeks of tinkering with it. I finally purchased a Dynajet kit and followed the instructions. My first start up was smooth and no issues with fluctuating mid range. The quad now has a nice crisp throttle response. The previous owner had 10 sizes too big of jets. This kit resolved my problems. Extremely happy!

The bike runs great easy install worth every penny

Seems to work ok. Considering I only needed one jet and a the needed the kit is terribly over priced for the nearly unrecognizable performance gain.

This is a well worth kit in my mind. I would give a 5 star rating but there are drawbacks to this. Mainly lost 10 mpg.
But it does run better with more usable power.
Everything has a trade off.

Used these kits for years, have always been great. Wish they would include pilot jet though, but really not a big deal. They are always spot on with the tuning!

When I bought the kit it was simply to correct some carb issues. However, my buddy said he could tell a difference between his stock 400ex and my jetted 400ex simply from this kit. It won't make a world difference but every little bit helps.

worked great, cleared up the off idle fumble these bikes are known for.

-m-2007 HONDA TRX 250EX--

Was great exactly what I needed ! Proformance was great and gave me way more power

I have buy this product and it was the best thing that a do on that bike..it run great now..

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.

-m-2014 KAWASAKI KLX250S--

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!

-m-2012 SUZUKI DR650SE--

Very nice difference in felt response and power! Follow directions exactly and you'll be dialed.

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.

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.

-m-2014 HONDA TRX 250X--

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

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.

-m-2008 KAWASAKI KLR650--

Perfect kit to open up my xr650l it helped the bike run a lot better and helped it idle better to plus it comes with more than one stage kits for your bike

I purchased this for my ATV and it was a good investment.

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

-m-2017 SUZUKI DR-Z 400S--

dynojet kit was easy to install and had clear setup instructions. This and a new FMF pipe brought the 230 to life.

-m-2009 HONDA CRF230L--

Awesome kit, instructions ans support

-m-2013 HONDA TRX 250X--

My son and I ride a pair of hondas, 250 and 450. I have jetted them both using dynojet, and I cant imagine our units running any better than they do. Affordable price, good product.

Noticed power immediately!!! Great buy!

-m-2003 HONDA TRX 400EX--

Follwowed directions and it worked perfectly. Made it very easy

-m-2002 YAMAHA RAPTOR 660--

The only kits I use. Brainless installation.

-m-2005 HONDA XR650L--

The KLX250S comes pretty lean from the factory, so a jet kit is a must. This was my second time taking apart a carb. I watched a few videos before I did it. The instructions were pretty clear. I left the air box stock for now, but depending on how it feels, I may pull out the snorkel. Overall I am very happy with the purchase. RMATVMC always has the best prices, ships from the warehouse quickly (unlike others that take 2-4 days before they ship) and arrives quickly.

Just like the title says. read the instructions. Installed the recommended jets. Started right up and only required a small amount of mixture and idle set screw tuning. Throttle response is spot on and no more factory lean bog.

small difference in power, maybe once i change exhaust it will help more

Along with an aftermarket exhaust and air filter you can expect some good power gains. Excellent product

This kit came with everything I needed to dial my bike in, noticeable power increase and throttle response. I also put in a K and N air filter and "de-snorkled" the air box. Very happy with the results

Purchase a pilot jet separately, the kit does not include one. Overall good kit.

The kit has easy to read instructions and really improves throttle response. Don't expect huge gains of power, that is not what its all about. It allows you to open up factory restrictions and help get rid of quad asthma. I did have to go to my local dealer and pick up a bigger pilot jet which was around $5. The pilot jet will fix the first 1/8 of throttle response problems. This kit fixes the rest of the throttle zones.

Gave my quad the wake up it wanted! very impressed and will be doing this with all my quads from now on

Nice kit but stock main jets

i purchased the jet kit only to find out that i dont have the correct carb for the kit. the one i received from rmatvmc was the 3111.001 which is for the 05 drz400e, not realizing there are two different carbs that came in this bike. the jet kit i received is for the keihin fcr carb and i have the CA model mikuni carb which is a different kit. its part number is 3111CA.001 it wasnt rmatv's fault so i am still very happy with the company. just bummed i've gotta wait for the return and to find out if they carry the right kit for my carb.

Everyone LOVES to jet their carb. whether its just making fine adjustments or jetting to add a pipe or air box, this kit will get it done for you!

Great kit, comes with everything you need.

just a little smother throttle response & warms up faster was about all.

I was having serious cold start issues on my girlfriends bike. Between this and a K&N air filter it starts up fine on about the third kick from cold. It would get 5 stars if it started first kick when cold. It is important to note I rebuilt the carb on this bike with this jet kick after the bike sat for several years when the P.O owned it. So maybe all the bike needs is some more hours on it. But once the bike has been ran it starts quick every time and has added a few ponies over stock. Much more enjoyable to ride, and no more stalling makes her much more confident in her machine and allows her to push her self knowing the bike won't be the problem.

I have a completely modified engine, a duncan racing exhaust and run a open air box, this kit had a extremely helpful jetting guide. I followed the guide and had perfect jetting on the first try! Lots of extra jets for different setups and elevations.

Machine this part was bought for: 1998 YAMAHA WARRIOR 350

Awesome product. Would buy again. When first bought, I ran the stage 1 settings. Big difference over stock carb settings. Modded my intake and went to a stage 3 kit. Jetting suggestions were very accurate. I had to fine tune to actual bike specs, but the guidelines made it very easy to get dialed in.

Installed the needle and main jet within 10 minutes (aside from plastic and tank removal) and didn't even have to remove the carb. my quad has never ran better i definitely recommend this product

I bought my wife a 250z quadsport for Christmas & wanted to tune it up a bit for her. So after looking online at alot of reviews, the quad kids were saying that the DynoJet kit was a must. They werent lying! First I cleaned the carb & installed a Moose rebuild kit w/ the oem size pilot jet to freshen things up. Then I installed the DynoJet kit (which was super easy) to our sea level & mod specs which was under 3000' w/ the airbox lid & baffle removed. I then had to order an adjustale air/fuel screw for a DRZ400 from Keintech to dial it in. After all that, this little 250 rips for what it is & was. I was very surpised at how much more rev she had. Its actually a fun little quad now & great for my wife. The only issue I have is that it doesnt come w/ a new pilot jet. Its just 1 more small jet that would complete the kit I think. They come w/ carb rebuild kits, so for the price they could throw it in.
