Back when I was checking the old/original two stroke piston rings for the gap in the cylinder after the block was checked to be in spec by machine shop and they de-glazed it with cross hatching, the OEM ones had a very small surface area to measure end gap.
That was a problem because it made measuring the gap difficult, and light marks were made on the cylinder wall by the feeler gauge. I can still see the cross hatching marks where the mark is when looking at it from an angle, it just made a line with darker grey color.
Do I need to go and buy a ball hone of the correct size with 320 grit and re-do the 45 degree cross hatching on the cylinder for the new piston kits?
