Message:   Florian,

Generally if the machinist has both the block and the pistons, then he can measure the pistons and bore the block accordingly. The measurement should have been 67.6mm (67.2 is standard). He should bore /hone the cylinders for a clearance of 0.0635mm if they are forged pistons and perhaps 0.0700 if they are cast pistons.

Never rely simply on what is stamped on the pistons, ALWAYS let the machinist measure and compute the piston clearance to determine the bore size.

Regards
Paul
