venturi size will depend on where you want your powerband to be

38-40mm venturis will be good for lots of midrange power,and good driveability. bigger venturies will give you more peak power but your mid range will suffer

my 13b street port has
205 fuel
200 air

44PHH mikuni side draft style.
very thirsty lol. But it also is 8 degrees outside. I think it has 40mm venturies...
