What size engines is this carburetor kit designed for?

The S&S Cycle Super E carburetor has a 1 7/8 inch (47.6mm) bore and is designed for engines up to 100 cubic inches in displacement.

Does this carburetor kit come with everything needed for installation?

The kit includes the Super E carburetor, an S&S chrome teardrop air cleaner, and an adjustable accelerator pump. It is recommended to consult the manufacturer's installation instructions for any additional hardware or specific setup requirements for your Big Twin model.
