I have not found any pro's and con's of Nickel-Silicon Carbide (NSC) plating for cylinders.
Roger Ditchfield, who is doing my;
heads w/ billet cams
balance, lighten, pollish JE pistons, with crank and rods
lower engine case mods for down pressure
believes it to be "NOT worth the money in my opinion"
Hord likes it for his RC builds.
Anyone out there that does engine builds or knows (current) engine builders for race bikes have any opinions on this plating process.
