the best mods in my opinion to do that wont break the bank is get a nice port job, adjustable timing plate, vforce reeds, prodesign cool head with high comp. domes, with some nice t5 pipes. other mods to do in the future is to get rid of the shitty banshee suspension and upgrade your aarms and swingarm. that can be EXTREMELY expensive though but makes the biggest difference on how your bike rides.
