Will this work?

would this 39mm carb off a wr400 work on a 2001 400ex. also how hard would it be to get the jetting dialed in here is the carb here (http://cgi.ebay.com/ebaymotors/39MM-FCR-Carburetor-Carb-400ex-Z400-WR400-Preditor_W0QQitemZ4576490017QQcategoryZ43979QQrdZ1 QQcmdZViewItem)

Idk if it will work

But fyi the Ebay link doesnt work,they havent been working for awhile

[2001300exguy]

ok well heres the part number 4576490017
would it even make that much of a difference?

[JDiablo]

Thats kind of alot to spend on that carb,if it was maybe like 80 dollars i would say go for it,you could always resell it but 210 is kind of alot,sorry to say

[2001300exguy]

o i know i didnt intend on using buy it now i was hoping it wouldnt go for to much and just bid at the lest second

[sandrabbitt]

not too rob your post or anything like that butt does any body know anything about the carb on the yamaha yfz450
(or yzf i never get it right im asking about the quad) ive heard it is a 39 fcr and would work well for a 440 ex due too the fact (i think) that the ccs are real close (ie 439cc on a yfz ?? ) some one told me they were identical too the 39 fcr that everyone buys for $600 and ive seen them go cheap used.

well the cc's dont really matter as much as the porting done on your head. I have the fcr 39mm made for the 400ex and it's a truly awsome carb. I wouldnt recommend putting anything bigger than a 39mm on a 400-4??ex because it will be too much! Check out ebay, there cheap on there used usually. You dont want that tps(throttle postioning sensor), you dont need that and its a pain in the ***.

so what other carbs will fit on the 400 with out huge modification, like i know the 450r carb needs a new intake boot made.
