If you’re looking to maximize that bike, start with thoughts about the exhaust and engine controller.
The hot ticket is: a good controller (I’d use a Maximus) plus a good set of pipes, an aftermarket intake (not just a K&N filter in the stock airbox) and a set of aftermarket cams. We’ll call it the stage 67. 😜
