Default Want F4 motor mods

Hello there, I'm new to this forum so don't be to rough on me. I have a cbr f4 motor in my mini sprint that I race on dirt ovals and am looking for some performance parts to make my motor put out some more horsepower. Any ideas would be great.

1998 and older engines are open. They must be normally aspirated and no larger than 637cc.
1999 and new will be U6SA.
