Nickel silicon carbide plated cylinder. Because boring out the cylinders would reduce the thickness too much their process is to cut the cylinders down to the base of the water jacket and install new aluminum cylinders coated with a nick-a-sil plating ie nickies. Someone else may have a better description of their process but this was my observation.
This is the original cylinder this one was on the verge of a de-chunck.
