Honda makes three piston sizes for the H23: standard, 0.25 over, and 0.5 over
what unit of measure are they using? would it be translated into the more common .025 and .050 measurements when talking about the overbore?

Honda always uses mm in order to measure.

skool me here.. If one was to get the .5 overbored pistons and new sleeves what would that make the displacement?
