    Need Help With Jetting.

    I have a 04' WR450. I would like to get it jetted so very minimal changes will need to be made throughout the summer. I will be riding at an elevation right around 1000' and in temps ranging from 65 to 90 degrees. Mods that have ben done already include: throttle stop cut down, airbox snorkel removed and side holes cut out, grey wire disconnected and a pmb insert in the exhaust. Right now i have a 170 main, 48 pilot, 40 leak, and 72 starter. The air screw is 1 3/4 turns out. The needle is the stock 04' with the clip in the fourth slot. I dont want to spend another $70 on the JD kit since i read the stock 04' needle is pretty good. The bike ran like a raped ape but with a bad low end bog with this setup without the pmb insert. But now after the insert it runs like crap and i am looking for a new starting point for jetting. I looked through many many threads and finally decided to make one of my own with my specific setup. Thanks for sticking with me and any input you have would be greatly appreciated. Im a jetting noob.
