Thank you Ryan for sending me the sheet.

Here is the spec sheet:
These are the design specs of the piston. This does not include clearance specs. The spec in here that says 81mm is the "basic standard bore" spec the piston was designed for.
Just because it says 81mm doesn't mean: "well Earl, i guess we just bore em all to 81" Anyone who has had an engine machine shop class will tell you that.
