250f. There are 3 of them that race locally here. All of them are yz250f's in 400ex frames. I have to give SideWaysSam some credit though he beat 2 of them at the last race and he races a 300ex with a stock engine. There really fast though...They will pull away on the straights....

I wouldn't use a 250x frame. I would go ahead and try and get a 400ex, or a 250r frame.
