I want to up the go in my ST170 to over 200bhp. What's the best way??

I already have a 1" 3/4 header on and the standard inlet has gone in favour of bike carbs...

I have a set of 43mm throttle bodies to fit and am wondering about the cams? Do I junk the VVT and fit a set of performance jobs, if so which ones?

I'm looking for between 200~220 to start then a supercharger may get fitted.

Any advise please??
