I opened up the airbox and exhaust and then used the JD Jet kit to tune the carb. I used the recommended settings based on my application and now my bike screams. It is surprising what a difference this has made in power and response."

JD Jet Kit JD Jet Kit JD Jet Kit Cobra26 (Anacoco, LA 71403, USA) JD Jet Kit, 2012 CRF 250X "Just installed this on a new CRF 250X after break in fluid changes. Instructions are ..." "Just installed this on a new CRF 250X after break in fluid changes. Instructions are simple and detailed enough to get through the procedure in a couple of hours. Take the time to do the Closed Course Competition Airbox mod while you're at it- this is also explained in the directions and really complemented the fueling the new jets provides. If you are using the stock air filter, remove the restrictive metal screen while it's out as well. My bike was completely stock when I installed this kit so the hangups I experienced were related to emissions equipment. Go ahead and lift the rear subframe and drop the rear shock. It will save you the headache of figuring it out later since it's not in the directions. The kit can be installed while the carb is in the bike if you disconnect everything and have good dexterity it's much easier out of the bike. Use the recommended settings in the instructions for setting the fuel screw and selecting your main jet for altitude and existing mods. I changed out the pilot jet and used the 160 main jet along with the low altitude needle as recommended for near sea level altitude and intake modifications. The bike instantly idled better and was willing to do so with less choke on warm up. It will sound healthier and your exhaust smell will sweeten up with the right mix of hydrocarbons. Throttle response is outstanding compared to stock and getting the front wheel up is much easier, especially in second gear which really helps on trail obstacles or favorite hooligan launching sites. Recommend this kit to anyone who wants to take the guess work out of making a custom set up and may change their settings again later. Definitely the way to go to fix the lean factory jetting options on the make and model I installed it on. Thanks to Motorsport for quick shipping so I could try it out over the weekend!"

JD Jet Kit JD Jet Kit JD Jet Kit Valued Customer (San Marcos, CA) There's the power! "After performing the CCC Airbox mod and installing the JD Jet kit with a Stock 450R ..." "After performing the CCC Airbox mod and installing the JD Jet kit with a Stock 450R exhaust on my '08 450x it was night and day! The JD Jet kit offers many options for varying conditions and the ability to dial in my bike was awesome. Followed the easy instructions and used their recommended setup. My bike starts first kick (or click) every time and the power is great. Highly recommend."
