How does this sound- a 2004 yz250f+262cc. Big Bore Kit I want to do this so I can race both 125cc. and 250cc. I don't want to get a 450 because that is to much power for me. I want a gain in low to mid which I heard this kit does. From what I have heard this would be legal in both classes correct me if I'm wrong. Does this sound like a good Idea. thanks in advance.
