I need jetting help by next weekend HELP!

[ZRFRACING22]

I just rebuilt my 04 400ex to a 440 with a stage 2 hotcam, white brothers slip on and an air filter, what do you reccommend (sp) for the jetting? I have my first race next weekend and need help fast, thanks

Do you know what elevation you are at, or will be racing at? I assume you have the stock carburetor?
