what can I do to my 02 400ex besides pipe, jets, and filter to get it to go faster.

 

Well, did you adjust all the slack out of the throttle cable? Did you remove the choke? Grind the welds inside the headpipe?

 

How exactly does removing the choke increase power?

thanks

I ouwld go with the Curtis Sparks pipe. I odn't know much about them but ones with the CS Pipe give my banshee a run.......SOMETIMES [img]i/expressions/face-icon-small-wink.gif[/img]

 

It allows more air to flow thru the carb unrestricted. It will actually add 1 or 2 ponies all the way thru the curve. It is actually a very popular mod an the 400EX.

 

Is it a real pain to start without the choke?

 

try a whitebros rev limiter. $100 (shop around, some sell it for more)
i just put one on last weekend and couldn't believe the difference!
it's literally a 30 second 'clip' on piece.
you get 1000 more in rpm and much more aggressive curve.
i used to have to 'pull' up a little in 2nd and 3rd gear to get the wheels to come off, now
i just sit back and blip the throttle! it's totally worth the hundred bucks and easy easy installation.
taking out the choke, i did that with my jet ski. i guess it helped, but i had it ported and polished as well at the same time.
all the choke is, is a flapper type device in the carb that, if removed, will have less restriction on air flow.
i'm sure it helps, but on my jet ski i had to add a primer kit to replace the choke.
for the supposed gain, not worth the work in my oppinion - i'm sure not all would agree though.
hey, every little bit helps! it's just a matter of how much you want to jack with it.

 

Will taking out the choke on the 300ex have the same effect as on the 400ex?

 

I've heard honda's are notorious for being hard cold starters (wouldn't know, my Z starts first try every time). So my question is being that you only gain like one pony, is it worth it? I mean if you're really serious about getting power, why not just do real power mods? Take'r up to a 416, and mod it correctly, or do a 440 kit. I dunno, guess it's just me, I wouldn't ever wanna be without the choke. To each his own.
