CA77 rings

Post by gideon » Mon Jul 11, 2011 2:23 pm

I opened up the motor and the pistons look pretty new. They say "CB77 and "ART" on the outsides and on the inside one says "0124" and the other has "015" on the inside. Does anyone know what they are ? Standard, OS ? Or do I have to mike the cylinders- who is mike. Thanks for any info you can offer .

60mm is STD piston size. If nothing is stamped on the domes it should be STD. 0.25, 0.50, 0.75 and 1.00 will be stamped on the top for the S1-4 oversizes.
