Stock banshee cylinder with iron sleeves aren't nikasil'd. Cast aluminum cylinders get nikasil because its a super hard coating and can withstand constant wear. Most of CP Industries cylinders are coated. You can have them built with sleeves. Millennium Technologies are the ones doing the electroplating with the nikasil. K&T does some damn good work.

Think the 540 motors had nikasil at one time to keep from wearing and cracking the sleeve. Could he wrong on that though.

You can have you cylinder nikasil. Just have to remove all steel parts from the cylinder because the cleaning solution they use is caustic and it will eat it up. But won't hurt the sleeve because it will he prepped for the plating. Just have to have someone that has a diamond tipped hone and have it ported before the plating. I have been told the.plating
