Frequently Asked Questions
How many carburetor rebuild kits are needed for the 1983-1986 CB450SC Nighthawk?
One kit rebuilds one carburetor, so 2 kits are required to rebuild the complete carburetor system. It is for the later Nighthawk carburetors, not the separate 1982 kit.
What should be matched before opening a carburetor rebuild kit?
Compare the carburetor model, bowl shape, jets, needles, gaskets and O-rings with the original parts. Model year alone is not enough when a motorcycle has replacement carburetors.
