My Experience is opposite. When racing Kreidler 50cc engines, we were more than happy to replace the chrome lining with NIKASIL after a porting job. The latter had a much better bond to the high silicon aluminum cylinder, and had micropores that would keep an oil film better. For that reason, the piston had an easier life. The standard Kreidler chrome plating was pitted for oil pockets, and was not as durable as NIKASIL.
