400ex carb

looking for a carb off of a newer ex mine is a 99 so it is a 32mm and i think that the newer ones are bigger.. don't want to spend a lot of money on a aftermarket carb..

All years are the same...except the float bowl design was changed in 2002 or so, to prevent overflow issues.
Bigger bore isnt necesarily better. It will give more top end hp, but will kill low end torque.
