For some reason now it seems like it doesnt get enough fuel when I start it up when its cold. I rolls over alot longer than it used to. But when its warm and I turn it off and start it again it fires right up. Could this be my pilot jet partially clogged or what?

well with the new cold weather of winter it will do that

when u use the choke does it help?

also before u start cranking it over , push the throttle a few times because the 400ex has an accelerator pump and it will squirt a little gas in the intake everytime u hit the throttle (this helps for throttle response) but just holding down the throttle wont do it

if those both dont solve the cold starts than, idk cause u say once its warm it starts right away so i dont think its your pilot

after i replied to this (this is an edit) i went to go fire my 400ex up
i dont have the choke in so there is less resistence. i had to push the throttle a good 20 times before it fired up

all carburated quads will have a little tuffer time starting in the cold.

yeah, I know that. The only thing is though, last year I don't remember it doing this. I mean its not bad, it starts and goes fine so. But I was just curious.

Honda's have always been cold blooded machines...
