Thank you motosport!

most other websites sell jets for my 99 YZ 250 but they make you buy four of them. Motosport has all the oem parts I need (as well as aftermarket) and I was able to just buy the single carb jet I wanted instead of having to purchase four. Shipping was quick and reliable too. Thank motosport! You guys rock.

WHO NEEDS FOUR OF THE SAME SIZE JET?

I rated this product poor because once you get the bike jetted you don't wear out your jets and certainly don't need four of the same size. It would be much better if there was a range of sizes in each pack. This is the same dumb thing that the dealer pulls when you go in to buy one jet. Just because Keihin packages them like that doesn't mean you have to sell them like that.

What size jets?
Where can I find jetting/tuning information? I'm looking to maximize my investment in an FMF Gnarly pipe for my '04CR250R. The bike cuts out at high rpms as if it starving for fuel.

What jets should I use for my YFZ 450 2006?
I have a yoshimura rs-2 full exhaust and am running the stock air filter with the lid on. No other mods. Around 700 feet above sea level.

There is not a specific setting I could give you for jetting your bike. It would really depend on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership??s service department to have your bike properly jetted.in jets.

Will this work for a honda xr100 carb?

No. It looks like your '03 Honda XR100 would use a different style main jet than this. We do offer a Moose Carburetor repair kit that would include a replacement main jet for your bike. if you were looking for a different size Main Jet than Standard for your bike I would recommend taking a look at the carburetor diagram for your bike in our OEM parts finder and there should be a few options listed for the main jets.

Any chance these could come in different sizes instead of four of the same?
4 different sizes would be way more useful for carb tuning vs. four of the same size jet. I don't anticipate wearing through 4 jets, however tuning the carb for different weather conditions or elevation change or application of performance parts makes more sense. 4 different sized jets would be much more useful.

Sorry, These are all sold as 4 packs of the same jets. You can order jets individually under the OEM parts diagrams for your bike. [ http://www.motosport.com/dirtbike/oem-parts/KAWASAKI/2003/KDX220R/CARBURETOR ]

The options the website gives you requires only 1 size choice and you do have to purchase 4. Call 888-676-8853 and ask for Motosport to sell you individual jets instead of the package of 4. PS: watch out for the shipping costs

These jets are only available in packs of 4. If you give us a call we can help you out with getting individual jets for certain models.
