When I used to road race old 2 strokes we would round out and smooth all edges & transitions on the piston skirt, even the hole for the piston pin. I realize a 4 stroke piston & rings are a tighter fit in the bore than a 2 stroke, so maybe this is not needed, since less chance of piston rock? The new AA pistons I have just seem to have sharp edges on all the skirts & was just curious if anyone dresses them before installation.
