My particular experience is that with a super mild cam, opening the ports (more than just a clean up) reduces the venture and vacuum action created by the tighter porting, creating less cavitation and atomization. One of my old Harley's was a perfect example. I ported it and put a larger carb on it with pipes but left the cam alone. Did it run a little better? Maybe,...once it was running. Kick starting it became a bear. Not enough atomization and it would drown the plug quickly. I cammed it and problem solved. Then it gave me second gear wheelies.
