If you get everything everyone has said and tune up the PC too. You will be set... I'm not sure about the engine. Prob your best bet would be sell and get more cc's... Try everything first though, you will be surprised how much you will gain. Heck, it will be like a new bike after you do all the stuff to it!

Yeah you can pursue major engine worked and forced induction but in the end you would be much better off getting a bigger bike.
