Where are you measuring your piston at? In all those examples they are measuring from the pin center and not from the skirt where the piston is wider. Even in the first example for the CP pistons it says that CP recommends .004 when measured from .005 from the bottom of the skirt but that he guesses that it would be .011 at the pin.

Update, this motor is a 2007 GX200 and I guess theyve changed since then. So I wasnt able to locate a HG or even piston rings for it. So I cleaned the stock stuff and just copper sprayed the HG. Runs like a champ.
