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.

A: 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.

A: Normally when installing a slip-on only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this slip-on. I would recommend installing the exhaust and riding the bike to see how it is running then tuning your carburetor from there if necessary.

Q: 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.

Please note: There are way too many variables in jetting to give you a recommendation that works perfect. Use these specs for a reference to help aid you with your specific bike.

A: I felt the need to let you know that the gnarly pipe does exactly that, hits hard on low end and signs off as if it was falling on it's face or starving for fuel as you say. I had one on my cr250r and it had no over rev same with my kdx 200, the stock pipe let the engine rev out but the gnarly hit hard on bottom but would carry any power on top. The gnarly pipe is called a woods pipe for a reason, it's for woods riders and luggers that only use low rpms and don't get to rev the bike to the top. The gnarly completely moves your power band to bottom to mid

A: 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.

Q: Any chance these could come in different sizes instead of four of the same?
2 years 7 months ago
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.

A: 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 ]
