All good tips, Rusty. I honed and cleaned my cylnders just like you described, and used about 220 grit stones to make a nice crosshatch pattern. I don't have a roughness guage, so I have no idea if this method left a smooth enough surface to keep the ring gaps from opening up too much during break in. The smoking that occurs, leaving a red light after a long idle only started after about 600 miles. Before this, oil consumption and smoke seemed totally normal for a rebuilt motor. Now, oil consumption is less, but I leave the embarrasing smoke cloud at red lights..... Everything is pointing to piston rings that did not seat right during break in, but maybe Degreeoff1 will discover something simple that is causing his motor to do the same thing
