smoke

[sica]

what does it mean if when i crank up my 400ex for the first few minuits it is running it smokes(white smoke)
it has a dmc full pipe,k&n filter, rejetted(dont remember what i went to)

Sound like your valve seals. Mine does the same thing. I wouldnt worry about it as long as it doesnt smoke all the time. It could also be condensation burning out of the pipe.

if its white its more than likely condensation ...BLUE SMOKE IS OIL!!!!! now when u need vavle seals its will smoke a few puffs of blue smoke when u first start it
