SXR 2009 SXR 800 Mod stock carbs or upgrade?

[Moto44]

My ski has a Factory Pipe wet pipe and compression is at 180. I use the boat primarily for buoy riding. Looking for more performance out of my ski and was contemplating sending my stock carbs to Group K for true 40mm boring? Is this worth doing or am I better offer upgrading my carbs?

Novi, Groupk, and Blackjack can all modify oem carbs and they work very well, but nothing matches the bottom.end hit of a big set of aftermarket carbs
