Re: Correct me if I'm wrong
I would not run that cylinder or piston even in a used engine.
I do not see any porting or polishing at all.
The cylinder's chrome plating has a crack coming off of the transfer port cutout in the cylinder spigot. That spells certain doom as the chrome will flake in short time.
The piston has been dropped, deforming the edge of the piston crown and that will cause undue wear on the cylinder.
They both look like factory "seconds" or rejects that were swept up from the assembly line floor.
