Nearly 100HP/L out of a single is pretty decent engineering. Power gains would come from shifting the torque curve higher and extending redline, thus at the expense of economy and mid-range torque. If you want to experiment with tuning, it would be better to start with a milder engine.
A simple, free, instant mod is to delay shifting. If you regularly hit redline at WOT, you'll benefit from more power. The most cost-effective way to get more power is a second bike, something common like a Ninja 500 or CBR F4i depending on how streetable vs. fast your tastes fall.
