Luke answered a question like this yesterday in the "washing and waxing section" that was asked by 67 Polaris. It's hard to tell how deep the scratches are but I think the same advise that Luke gave yesterday would apply to your problem. I think the thread was titled "really need some advise" or something like that.
Just cause it's loud doesn't mean it's fast and just cause it's shiney doesn't mean it's protected. Remember, going fast costs money, so how fast do you wanna go?
