553cc inline-four engine removed from a 1990 Kawasaki Zephyr 550 with only 2,500 original miles. This is a "time capsule" motor that has spent most of its life in storage. Mileage: ~2,500 miles. Running Condition: The engine ran before being pulled. Shifting Note: The gears are currently hard to cycle through. I think this is due to the bike sitting for a long period, causing the old oil to gum up and the plates/linkage to get stiff. It likely needs a fresh oil flush and some heat cycles to return to smooth operation. Included Accessories: Starter Motor: Included. Sprocket Cover: Included. Shift Linkage: Complete linkage included. Fitment: 1990–1993 Kawasaki ZR550 Zephyr. Seller’s Note: It’s been sitting, so it’s a bit dusty and needs a weekend of "TLC" (fluids, cleaning) to get it back to its prime. Perfect for a high-end restoration
