JD Jetting Jet Kit JD Jetting Jet Kit WRGuy - Michigan, USA Very Good "Recently installed this jet kit in a 03' WR450 after installing an FMF Q4 slip on exhaust. I ended up removing the O ring on the accelerator pump as it gave a bit too much power for trail use. Directions were far better than the ones that came with other big name kits and the performance exceeded my expectations."
