fcr 41 mm on a 400ex

[gotahemi2004]

i was wondering what to exspect power wise with my current set up... will it make a big diffence is torquw / top speed, or what?

Do you have any motor mods? I think you would at least need a cam and some port work or possible bore kit to really feel a difference with a bigger carb.

well i got the k&n powerlid ,k&n filter ,, full lrd exhuast.. and honda put in a small small bore from warrenty work... i got a rev box.. but nothin internally done...

Do not expect a tremendous gain!!! If you had a 440 or a pro am kit it would be a totally diffirent bike, but stock bore?? The bike actually might get choked from the fuel??? I am unsure on that but that is what Iwould expect.

You'd be better off with a 39mm FCR. Throttle response should be significantly improved. Low to mid power noticeably better. I wouldn't think that the top end power will improve much if any without some more agressive internal mods. JMHO

well the thing is i found a 41 mm for a good price.. that why im going allt he way tot he 41 i just wanna make sure its not gonna be too much i guess

The 41 will still be worth it. Even more so if/when you do some int. mods.

if you found a good deal on it, buy it. if you don't like it, you can sell it and make a profit.
