Denny, I understand that you can streamline the carb and increase the airflow through it just like you can ports in the head. ("choke horn milled off, entry passages smoothed and flowed, butterflies and shafts thinned, etc.") What you are referring to is when I took exception to the impossibility that someone could "jet up" or "jet down", in other words change the flow capabilities of the carb simply by changing jets. Every time I see that in print, I go ballistic and do my best to bring a grain of reality to the situation. I DON'T CARE WHAT ANYBODY SAYS, IT IS NOT POSSIBLE TO CHANGE THE FLOW CHARACTERISTICS OF A CARBURETOR SIMPLY BY CHANGING JETS OR METERING RODS. THAT'S JUST STUPID.

A 750 is a 750 and will remain a 750 until someone does surgery on the mechanical parts of the carb.
