Like any four stroke, it will respond to traditional improvements in breathing. A free-flowing exhaust with a less restrictive air filter (with jetting to match) will wake it up. Beyond that, you can try a programmable CDI (although that can make it difficult to start). If you really want to get into it, you can port and polish the head, like Dan and Jerry have.
