Yz250F carb on 300ex

[Jake250ex]

would it work? what size is it? I think the acc. pump would make it easily better than any aftermarket carb setup out there.

you ought to try and get a whole 250f engine. these motors rip! i was going to do this to my 300 b4 it was stolen. you would probably still be able to run local 200/300 classes, but probably not at the nationals, because its not air-cooled.

i dont know if it will be an easy set up.
i have a yz250f and the carb on it is a lot more complicated than the 300ex. if you can get it on there you will need to change the jetting for sure, i believe the yz250f carb is jetted a lot bigger than the 300ex is because of its engine set up.
