Lots of things you can do. Depends on how much money and work you want to do. Common things are to put a high compression piston and hot rod crank. An easy and possibly cheap is out aftermarket exhaust on it. You could go in farther and get some new cams. A really easy thing would be to get some different sized sprockets.

First thing is pull the K&N off before it destroys your motor. Put a foam filter back on. Next, clean the carb, change all the fluids to synthetic and get a hang for the quad before getting all crazy. The 600 is a fast quad in stock form. After that a pipe is the next step.
