what fcr carb on 300

[shaungray89]

i have heard that the fcr dirtbike carb is a great improvement but what year dirtbike do i get it off and what size should the carb be what model should it come off of i have a 2002 300exl but its completely done over and i am running a 400ex carb right now

unless u have one nastily modded 300, stick with the 400ex carb, the 450 isnt much different, not really a big improvement if ur using it on a 300...

37mm off of a KXF or RMZ carb works mint. or a 35mm from Sparks/TC or a 37mm from sparks(only for highly built motors) or a 39mm off of a CRF 2006+ 250f works good too but is way to much for just the average bike. ;)
