Dynojet Carburetor Jet Kit


Every Dynojet carburetor jet kit is designed specifically for your machine to increase engine power, smoothness and throttle response. Each kit provides optimum performance throughout the rev range for maximum power and optimum fuel economy.

PartsGiant has a variety of jet kits on hand to meet your specific riding needs.

Choose the correct kit for your needs:

Stage 1 jet kits

Ideal for motorcycle & ATVs with a stock engine using the stock airbox, air filter and stock pipe. Stage 1 kits are fully adjustable to work with well-designed aftermarket pipes as well as stock replacement air filters.

Stage 1 kits improve throttle response and driveability. In most cases, power increases of approximately 5% throughout the entire power range can be achieved with correct tuning.

Stage 2 jet kits

Suitable for machines with a stock or mildly tuned engine that have a well-designed aftermarket pipe, a modified airbox and a stock replacement air filter.

Stage 2 kits are designed for applications where individual filters cannot be installed or for applications where airbox modification improves the engine's performance. In most cases power increases of approximately 8% can be achieved with the correct tuning of your carburetor.

Stage 3 jet kits

For installation on machines with stock or mildly tuned engines using a well-designed aftermarket pipe and individual, pod-type air filters. In most cases power increases of 10-15% can be achieved. Mind you, driveability may be compromised particularly with short stroke, high-RPM motors. So long as you're keeping the revs up, this usually isn't a problem.

Stage 7 jet kits

For race only use or for special applications, like the Yamaha V Max complete induction kit. Stage 7 kits are designed to optimize jetting for a given tuning specification or racing conditions.

Good top end power

By   on  Verified Purchaser

I had to make some adjustments from the Dynojet recommended settings, but the kit came with a bigger main jet so it worked out. I'm running cobra pipes with a K&N filter so it's actually got great flow. The DJ jet kit definitely improved power on the top end.


Thanks

As described.


Worked wonders

Worked wonders for my old 1982 Suzuki GS1100G! Second bike that I've used a Dynojet kit on highly recommend it.


Jet Kit works great

By   on  Verified Purchaser

The Jet Kit works great. Better throttle response.


Stage 3 all the way

By   on  Verified Purchaser

Bike fired up immediately! Good throttle response when run on stand, couldn't ride due to winter weather. Very happy with the Stage 3 application recommended by Dynojet - pod filters, full header and open muffler. The bike is ready for final tuning in the spring-it's snowmobile season now 😁


Check with forums for correct jetting.

By   on 

Product is good and various options for tuning. I would say do the homework for your jetting needs. Check your bike forum, they know best. I used the recommended jet on stage 2 because I upgraded exhaust and intake but it ended up fouling up my plugs and rear cylinder on my twin wouldn't fire due to excessive carbon build up.

Could have used better instructions. I have repaired rebuild several carburetors and this one I was letting my son do. I caught him before he drilled out the wrong plug for the air fuel mixture screw. Other than that it’s a good little kit.

Just finished the test run and i must say I am very pleased with what I accomplished with the snorkel mod K&N air filter and this Dyno jet kit. Wow, what a difference it made. Whole new bike, definitely woke it up. Sounds awesome too. I drilled my 2 into 1 with a 7/8" key hole saw and it sounds awesome. Getting a lot of compliments. Best money I spent on it so far. Oh, by the way, I have a 06 aero 750 but it runs more like a 900 now, lol

Just what I need to go with my pipes. Huge difference in power! So fast!

Answer Question

I want to run drag pipes ( straight pipe) on my 85 honda shadow 1100c, what stage kit will i need?

For your needs, as long as you're not doing much on the intake side, such as removing the filter housing, then a stage 1 jet kit will do the job with a set of straight pipes. Generally speaking, you only need to go beyond a stage one kit if you're doing more than putting an aftermarket air filter on the intake side. That is, in addition to an exhaust, of course. So long as you're not fooling with things on the intake other than an air filter that fits the stock design, a stage one kit is good for your needs with that exhaust.

By Staff
Answer Question

In addition, the Raptor 660 Yamaha jet kit requires that you modify the intake snorkel (only requires a sharp knife) so as to increase intake performance. With the latter job done, your machine meets stage 2 requirements. Best of all, the included instructions explain exactly how to go about modifying the intake snorkel and also, how to install the components included in the jet kit.

Answer Question

Suzuki ltz 250

I have a 2005 suzuki ltz250 and just changed the muffler and it says to change the main jet to a 138. Does this kit have the 138 do i need one that big and do i need to change out all the jets. Also it is sputtering just as i hit the higher rpms

The sputter at high-RPMs is certainly a sign of inadequate fuel delivery, so this jet will will help out with that problem. And the kit does indeed include a 138 main jet. If that's what the instructions for the muffler you have call for, then it'll probably get you pretty close to your ATV's ideal fueling requirements. There are also a few other components in the kit that you'll need to install in order to get the most out of your new LT-Z250 exhaust arrangement.

Will this work if I have a high flow air intake and a straight pipe exhaust with no baffles? 2005 Honda shadow spirit 1100

The Stage 1 kit jet kit for the VT1100 Shadow Spirit would probably be a good match for your needs. It'll certainly be a lot better than stock! Though, when running straight pipes, you're going to be running the biggest jets included in the kit right from the off.

And if that turns out not to be enough fuel, just let us know and we'll find a bigger set of jets to fit.

But rather, the included fuel needles and drill will be more than sufficient for correcting the fueling issues you're having.

Answer Question

What is included in the kit for 1998 Honda Aero?

The bike I purchased has to warm up for awhile and sounds like it wants to stall if I pull back the choke to soon. It's also hesitant when starting but once it gets going she's good to go. I suspect the previous owner never jetted the carbs when he installed Vance & Hines longshot original pipes. One of the pipes is discolored as well. Everything else is stock. I'm thinking Stage 1 kit?

It sounds more likely that you've got carb issues in general, as opposed to jetting problems, and the Dynojet kit we have on offer probably won't do much to fix that for you since it's really designed to deliver more fuel while under way, and especially at bigger throttle openings. Your best bet would be to service the carbs in their current form before modifying fuel delivery with this, or any other jet kit we have.

By Staff
Answer Question

I have a 400ex and I just bought K&N powerlid and air filter as well as full sparks exhaust too and my question was what stage should I use 1 or 2?

Answer Question

I added a DG slip on to my 2012 Kawasaki KLX250S. Since then my engine seems to backfire when i back off the throttle. Will re-jetting solve this problem? Also, does this kit include jets and needles for Stage 1 and Stage 2?

It sounds as though your machine has a poor seal somewhere on its KLX250S exhaust system or in the airbox. A jet kit isn't going to solve those problems. Your best bet would be to have a look at the seals throughout the exhaust system and, just as importantly - around the airbox and carburetor boot. If there are any gaps there, it'll cause gases to leak into the exhaust when you close the throttle and the bike will backfire. As for your second question, in the case of the Kawasaki KLX250S jet kit, yes - the Stage 1 & 2 kit from Dynojet includes everything you need to correctly jet a stage 1 or stage 2 set up on the KLX250S.

Answer Question

2001 xr650L with after market pipes,deleted emissions and Honda Bore kit installed

What jets should I use?

If it's a XR650L big bore kit that you've got on there, you should start with the largest main jets available in the stage 1 jet kit. With that, you should have a pretty good idea of which direction to go. In most cases, that'll get you within the ballpark, but without having the machine here to examine, it's really difficult to say whether or not better work could be done. The good news is that the included instructions do a pretty good job of explaining how to go about installing and configuring the jet kit on your specific machine. With that, you should have a really starting point to work from and improve upon.

Answer Question

I have a 2002 Honda shadow 750 spirit that I just bought and it came with a cobra pipes and a k&n air filter but it seems that the last owner did not mess with the carburetor and I getting a lots of back fire in de acceleration and some times it feels like it's not getting enough fuel in low speed. Will this kit will help me to eliminate those problems?

This VT750 Shadow 750 jet kit will help with the low speed fuel delivery, yes - but the backfiring is more of a problem with how the aftermarket Shadow 750 exhaust was installed. In many cases, backfiring is caused by a poorly assembled exhaust. Your best bet would be to examine all of the connections for the exhaust to make sure there are no gaps that could cause leaks. Furthermore, the intake is another area of concern. Make sure the entire intake manifold is bolted down securely. In this way, you can be sure there are no air leaks that would cause excess fuel to be pulled into the combustion chamber to cause backfiring. Once you've done this, if the bike still feels like it isn't fueling properly, then it will be time to adjust fueling with this jet kit.

Answer Question

I have a 1994 Honda Shadow VT1100c and wanted to remove the baffles. Will this prevent damage to the engine due to the lack of back pressure from removing the baffles?

Back pressure isn't so much of an issue when removing baffles, or installing a different exhaust for that matter. It's an excessively lean fuel mixture that causes problems. If your bike is already running well with the exhaust that's currently installed, then you'll probably only need to make an adjustment to the pilot jet or maybe change the circlip's position on the fuel needle. The installation of a new jet kit isn't required. It's when you're going from a stock exhaust to a complete exhaust system and/or air cleaner kit that you really need to make fueling adjustments, otherwise - tweaking the carb as it is should be all you need to do.

Which stage kit do I need for a 2009 ninja 250r that is stock but I will be modifying the air box and will be putting an aftermarket echaust?

Also, is it ok to put this stage kit into just a bone stock bike until I get the upgraded exhaust etc?

The stage 2 kit would be ideal for your needs, but only after you install an aftermarket exhaust. Installing a stage 2 jet kit on your bike with a completely stock intake and exhaust is not recommended since it'll be running far too rich. Your best bet would be to wait until you get all of the work done before re-jetting the bike.

Will the kit for a Honda shadow 750 aero work on a honda shadow spirit 750?

Dynojet's jet kits for the Shadow 750 Aero and the Shadow 750 Spirit are significantly different. Due to this fact, they're not interchangeable. As you've noticed they only produce jet kits for 2001-2006 model year machines. If it's a newer bike that you have, check out Cobra's Carburetor Jet Kit for the Shadow 705 Spirit. They build jet kits that'll fit 2007-2009 model year machines.

Answer Question

i have a 2000 katana 600f is this kit right for me

It really depends on how your machine is configured as to what stage of jet kit your bike needs. If your bike is mostly stock with an aftermarket air filter and/or exhaust system, the stage 1 jet kit will do the job just fine. If your bike's engine has had its internals modified (eg. ported and polished) along with a full exhaust system and a modified air filter/airbox - then you'd want to use a Stage 2 kit. Should your bike be used almost exclusively for racing purposes but is configured like the Stage 2 example, then the Stage 3 kit is your best bit. We say racing purposes due to the fact that the Stage 3 kits are designed to work best in the upper engine RPM range - something that's not too practical on the street. Stage 7 jet kits are for all-out engine builds on a bike that's to be used for racing only.

Answer Question

I have a 96 intruder 800, when pulling the throttle back I get a sputtering sound and a lot of backfiring. a carb jet kit should do the trick right?

Unless you've recently installed an aftermarket exhaust or put a new air intake on the bike, you shouldn't need to re-jet the carburetor or otherwise adjust fueling. Most likely, the issue would be a loose head pipe or muffler connection which then causes the bike to run lean. This, in turn, would lead to the sputtering and backfiring that you've noticed. Have a look at your bike's exhaust system and check for loose bolts and fittings, In addition, check out the exhaust ports and make sure those gaskets are in good shape. Once you've tidied all of that up, you should be all set.

Answer Question

I have a 2007 Honda VTX1300R with a Vance & Hines exhaust. It sputters quite a bit and coughs until you get it up into higher RPM. Will this kit help? Can I do it myself?

I am fairly mechanical but don't know about carburetors, etc. Is this something I could do myself or do I need a professional?

It sounds as though you do have a jetting issue. This would be especially true if your bike hasn't had its carburetor modified to account for the better exhaust flow. The fact that the bike runs well at higher RPMs is due to the fact that emissions tests are typically done at 1/3 full throttle. Consequently, the OEMs don't have to do much to work with full-throttle power as it's not measured, so the bike runs fine when you really get the engine spinning. As for ease of installation, since the VTX1300 has only one carburetor, there's not much to it - just remove the tank, pull the carb off and follow the included installation instructions to get your bike dialed in. If you have simple hand tools, it'll take only one evening of work in the garage.
