Hi,
      I think the ring with the chamfer is the top ring, the chamfer is intended to help after a re-ring on a used bore, it minimises the effect of any wear ridge around the top of the cylinder wall from the old piston

Hi,
    Apologies to billy192 and bryanj, I can only go with my remembered instructions for my yoshimura rings, which were all black finihed, and were fitted as stated, there was a dot to mark comp. ring upper side
