does anyone know what the valves should be set at on a 400EX with a white bros all-around cam? I set them at .004 for now but would like to know the actual specs for future reference.

i can't tell you exactly but i bet that is too tight. the stock cam is .004 intake and .005 exhaust, and this cam is not agressive.
