no no, don't do that. that's expensive and the information around here isn't relevant to dynojet jet sizes. go to ronayers.com, and order the N1TC adjustable needle, a 40 pilot jet, the tiny washer and circlips, and whatever main jet you need be it 128, 130, etc. this stuff is all keihin stuff and thus made by the carbs manufactuer and the search info you'll be looking up all pertains to these jets. when you buy dynojets, everyone pretty much scratches their head because no one can help them. also, buying these parts is cheaper than buying a kit with stuff you won't need or use.

also, don't get the 2-bros. buy a BigGun EvoX full system for nearly the same price as the noisemaker. you'll be glad you did as it adds real power, throw on a 13-tooth front sprocket, a Uni-filter air filter and smile the rest of the day. go to www.motorcycleparts.biz for your BigGun. also if you want your bike to run cooloer, yank off the emissions crap and cap off the three openings. it's easy and it cleans up the underbelly of your KLX as well. don't be intimidated to take the tank off. the epa stuff connects to the front of the engine and back under the tank to the carb/airbox. good luck.

I forgot, the part #'s for all the above mentioned parts are on a sticky thread (thread always at the top of the forum) and you can copy and paste each #into your shopping cart. trust me on this.

 

nah, don't listen to these new guys. the founding fathers around this forum knew their stuff, and the N1TC needle is the one you want. if you buy the DJ stuff, it's like going to Germany and not being able to speak their language. no one will know how to help you cause Dynojet is just a name that attracts people to their kits, most of the time you buy a kit and use 2 or 3 things, and the rest just sits in the clear little plastic container. you guys know this is true.
