Topic: Riken Piston Ring Order

[The Gurg]

Bought some Riken Piston rings. Trying to determine the correct order of the upper and lower compression rings. CB750K5. Riken part number H-300024 STD.

The first ring in the box is a carbon colored ring with a silver band around it. The next ring is very slightly lighter in carbon color, but has no band. Next are the oil rings.
