    What comes in a JD jetting kit?

    I have an 06 450X and I'm going on a trip to the coast to ride the dunes. I recently put a full Dr.D exhaust system on (not the perfect fit), but I'm way to leaned out.

    So naturally I trusted my dealer, went over there to ask them if they had any jetting kits, being the noob I am. They went ahead and ordered me the FMF power up kit. Apart from their number system being different, they didn't even provide a big enough main jet. The biggest is a 144, and on top of that, they didn't give me any different sized pilot jets. With my fuel mixture screw being 2 and 3/4 to idle right, i need to go a size down right?

    I was just wondering if the JD jetting kit would come with all the main jets I need, as well as pilot jets. I know everyone here seems to stand by them, and thats good enough for me, even if I do end up throwing away 60 bucks.

    With a JD kit, you typically get:
    - 2 custom needles (red and blue)
    - main jet
    - pilot jet
    - AP o-ring's

    What you are paying for is the needles, which are custom built by JD. Jets are a few bucks each and can be ordered online from several places. I've used JD kits and would recommend them.
