Original set of four Keihin CVK carburetors removed from a 1990 Kawasaki Zephyr 550 (ZR550-B). This is a complete assembly, still connected as a bank. Condition Details: These are in Fair condition and will require a thorough cleaning and likely a rebuild before use. They have been sitting and may have old fuel residue. Mechanicals: The butterflies move, and the slides aren't seized, but they haven't been tested on a running bike recently. Fitment: OEM for 1990–1993 Kawasaki ZR550 Zephyr models. Maintenance Tip: If you're rebuilding these, you can find All Balls Rebuild Kits or Parts Unlimited Kits at retailers like RevZilla and eBay. Seller’s Note: Perfect for someone who wants to restore an original set rather than buying expensive new replacements. Sold strictly as-is for parts or rebuild
