Hello I have a stock 2007 CRF 450 and I would like some tips for making my bike run strong @ Mammoth. I would like to know the main jet, pilot jet, clip position,air screw and whatever else you would recommend. Thank you. [email protected]

you'll hear it here a lot but your best best is to take a JD Jetting kit with you. Jet it for the altitude of the race and when you get be prepared with +/- 1 jets and to raise lower the clip position.
