Removed Pistons and Cylinders from New 340 Kawasaki Free Air engines, Only test run at the Kawasaki factory in Japan. Comes with everything pictured. Pistons with rings, Piston pins, Piston pin C clips, Cylinders with attached intake as pictured, Original head gaskets that were on the engine and are reuseable and a new set of base gaskets. The old base gaskets will need to be removed by buyer. There may be more or less gasket on cylinders than pictured as I have many sets for sale. Thank You for looking.
