This Kawasaki Ninja ZX6R/636 engine/motor is not working and is available for purchase. The brand of this engine is Kawasaki and the manufacturer part number is 2019, 2020, 2021, 2022, 2023, ZX636. To be as transparent, this engine blew on me from a mixture of preexisting issues. Several parts are damaged including the engine mounting points, a connecting rod has punched through the engine block on one of the cylinders. In addition I have seen metal shavings in the air box so several things are bad within the motor. I personally do not have the time to do an engine rebuild and am willing to accept reasonable offers. The engine had 3000 miles prior to blowing up. From what I can see all the valves are intact, I can provide more pictures upon request.
