Good dayyy, As per title i need some carbs with port sizes at least 40mm+

again anyone have anything?

oddly enough yes. I just put zzr 1200 carbs back on my car. I have a set of zzr1100 going spare, They are fine althoough i changed the float bowels so they have the 1200 bowls that have fuel cut offs. these should not cause a problem if a feed is put tp them.
