You have a ported 1300 single pipe and you took the e.f.i off and went to carbs?
I may be smoking crack, But this is your 2nd question in 30 minutes that doesnt make sense. It almost seems like questions that gpr1300 powerhouse guy would ask.
If i am wrong, I apologize...

NOVI carbs are freaky when trying to find the right main jets..PM sent. They are MUCH different than OEM's or any other carb jetting specs..believe me , I found out the hard way.
