choke on 400ex

why do u guys take the choke off your 400exs?

[Wired]

well i think the main reason people do it is because the butterfly causes alot of turbulence within the carb and doesnt let air flow smoothly through it. i took my choke off and i did in fact feel a difference in throttle response, some people dont but some people do. my 400ex doesnt start any harder either, almost starts easier since ive done it :macho

What he said.....

I took the choke off mine about a week ago, I noticed an improvement in throttle response and power.

Time well spent.

Do you have to re-jet after taking the choke off?

[Texan32]

Most guys are taking it off in conjunction to putting in a 40 or 42 pilot jet. You don't have to rejet, but you are probably going to have a little trouble when it starts getting colder again...

then yo jetting is wrong or your tryin to start it the wrong way. I think the choke on the 400ex is the worst thing about it,,it never worked for me on both my 400ex's..:confused:

If your located in an area with moderate weather temps,,say around 70 degrees and you can't push the gas 2 times and hit the starter button and it won't start then you need ta fine tune your carb. I have no choke installed and I can go out in 50 degree weather and do the above and she comes to life and purrs like a kitten..

Its about an average of 90 degrees here. I can get her started just can't keep her started.

sounds like ya need to up the pilot jet a size or 2..it will fix your problem with starting..

next time i go to the shop ill pick one up
