Some of this information is very outdated. In the days of rough-honed, cast-iron cylinders, it was necessary to seat the rings before the cylinders glazed and prevented wearing the honing down smooth. The wrong oil, too little rpm and load, or even overheating, could cause glazing or even cylinder distortion. With the advent of honing plates, closer tolerances, fine honing stones, and moly filled rings, this became unnecessary...rings seated quickly on the polished cylinders, and a lack of wear was a desireable thing. With the Nikasil-plated cylinders on the Spyder, there is no cylinder glazing and no wear of the cylinder. Rings seat almost immediately.
