what size pistons do i need for barrels that mesaure 65mm chaps, standard bore size is 64mm...65mm would be 1mm oversize... piston should be marked +1.0mm |

You need to get them sized right first. You dont want to get pistons quorter mill to small or big do you.

if anything you should recruit a good machine shop and have them measure then hone the bores to properly suit the pistons...dont forget to chamfer the ports slightly afterwards...some places do this for you...most dont...give the rings a easier life |
