[QUOTE="davidd, post: 54882, member: 1177"] Vincent seems to be most concerned about high wear. I am not sure that the difference in the cast iron properties would yield a big reduction in wear. I know the Nikasil will provide very low wear to the bore. It will not reduce wear on the rings or pistons particularly if no air cleaners are used. I would go with the technology that is easily available and fits the conditions of the engine and the environment. I may have given the wrong impression about the Nikasil process. I think it is sprayed on the liner while it is in place after machining. It is then finished with a diamond hone. There is very little interference fit between the line and the muff as they are both aluminum. However, only the bore of the liner is coated with Nikasil. The top of the liner is not coated, as far as I know. David [/QUOTE]
