Add ports to your sleeve/liner, you'll increase fuel flow. As long as you can burn it, it will make more power, but it will likely use more fuel. So, what you said makes perfect sense to me! It SHOULD use more fuel!
Let me disagree with you little bit.
Are you sure that more ports = more power?
I can get more power from 3 ports sleeve then you can get from 5 port and my ports are much smaller then yours and not modified (tear drops etc).
It is not that simple make more ports, bigger ports and magic works. First of all you need put right ammount of mixture at right velocity at right time to the right place. And if any of this varibles is out of range-no power.
