Dude, are you fucking stupid? The white 450 is mine and the blue one is my brothers. Im sorry bud, they are stock. Our buddy has the 450r, its been ported, got a cam, and a pipe. So I think you should shut the fuck up. You have no idea what you are talking about. Ur prolly some stupid punk ass little buttfucker that doesnt have anything else better to do then to start little arguments and act like you know something. I dont even know why Im wasting my time on you, but I cant resist. Ur so fuckin dumb it makes me wanna cry.
