I'm building my 400ex currently and I'm putting a new bottom end and a 440 big bore kit on it and I'm looking to change the carb because it has a stock one right now and I was wondering
If anyone has any opinions on what to use I was told that a fcr carb is the way to go off a 450r but what year should I go with.... all help and opinions are very appreciated.

04-05 450r carb is what you want. plenty of write ups on the forums on how to do it. I did my 440 this past year with one.
