will a 07 450r FCR carb fit on the 400ex's like the 04-05 carbs will????

you WILL have to do some fiddling but it can be made to work.You'll need a 450r or yfz450 throttle cable for starters.Im not sure the size right of hand but it maybe a bit tight with a 40mm opening.Im using a fcr 39mm on mine from a yz400.If you insist you can make it work,its worth it imo:)
