Put a new pipe on it, a good high flow filter with a pre filter. Run no air box lid and have it jetted (assuming it is not EFI). You could also change your gearing. If you add teeth to the front and/or put a smaller sprocket on the back you will have more top end.

A raptor 660 is about 450lbs. When the raptor 700 came out, many found it to be much faster.
