Caltric Cast Aluminium Engine Cylinder Piston Kit Compatible with Kawasaki Bayou 300 Klf300B 1989-2004

Works fine. I have KLF-300A, and I needed to modify the timing chain bolt holes on the head so I could get those little guys in. The head bolts work just fine and didn't need to be touched. Also the my KLF300A timing chain adjuster would not seat all the way in. I ended up getting a manual adjuster off amazon which works just fine. Pre-Start/Ring Seating I had 118 PSI on the compression tester. At the same time I did a valve job as well and found my intake valve was past done. I would recommend you inspect the head and valves as part of replacing rings, wrist pin, rod, piston cylinder and/or sleeve. Be smart about it and do not cut corners. I now have 10 hours on it and I get 138 PSI on the compression gauge which is very healthy. The four-wheeler runs probably better than new right now.
