1999 WR 400 Carburetor Compatibilty Question.

Hi All:

A friend of mine has a 1999 WR 400 that is having carburetor problems. He is looking to possibly purchase a new one or a used one but is having trouble getting a firm answer on which years/models will cross over. Thanks for any input. c good

I put a 05 Yz450carb in my 99 wr400. Pretty much any fcr39 carb will work. Jd jet kit and it flat out rips

Bauten was wondering what else you had to do for the carb to work on the 99? ie...Cables,rubber intake boot,air cleaner boot does all this fit or did you use it off of the 05?
