I have an idea, but you should call Zippers. They will either ask then or may email / supply a data sheet form where you fill in the blanks with your combination along with average altitude where you are.

They are extremely knowledgeable, well versed in what make a street or race Harley run 'in-da-front'

I have done countless conversions on street Harley's in the past years from someone else's 'trick' carb to this or "G" similarly prepared - with nothing but smiles on the faces of my customers afterward. Tuning a long stroke air cooled engine is an art - and they have it!
