I just bought a 400ex with a big bore kit, pro circuit full exhuast, k&n airfilter and a 440kit. Im not sure if the quad was jetted or not so can anyone tell me about what sizes i should be running so i have an idea if it was done or not. Thanks

Really the only way to know if it's right is to do a plug check..;)

The quad runs fantastic but i just fouled out a brandnew plug, maybe it was a bad plug....

try going down 1 size for the main jet and let us know how it is then.
