    possibly, go down on the mj a size or 2 and see what happens from there. And like Rico said, stay off the choke brotha. As a matter of fact, just remove it, install a 42 pilot, go 2 1/2 turns out on the mixture screw, and your cold starting problems will be solved

    What I don't get is why people have to pump the throttle. My 400ex needs no throttle or pumping to start. Hit the starter, and it fires to life. My uncle has a 400ex that he slightly opens the throttle and it starts fine, but why do some people do that? Just wondering...
    I own a:
    Red 1999 400ex, Some mods, Filter, Skid plate, HMF pipe, etc.

    Hell yeah I'm American! And I pay $3.30 for my gas... How much higher is it going to get???

    Us people that pump our throttle have the choke removed. Easier than fighting the stupid thing until it gets warm
