Moving farward!

G'day, how do i make my zx9 r c2 baby go a bit harder? I bought it with a Kerker pipe which loses a bit of bottom end, sounds good tho! im not complaining mind, but i will have this bike for ages, i wanted one for years and lets be honest they arent pricey and best of all she is beautiful to look at, just want to know if there is a workshop in melbourne that i can go to with the idea of improving zx9r's reputation on the streets!
