Piston second ring

[pouchy750]

I've got the crankcases back together, thanks for the advice on the oil rings.
I have put the pistons back onto the conrods & looking to install the piston rings.
In the Honda workshop manual the second piston ring is shown as having a taper along the whole width of the outer surface of the ring.
On the Honda rings I have obtained, I assume that the second ring is the one with a slight chamfer on the top outer surface edge of the ring only?
The top ring has no difference to the top & bottom outer edges of the ring.
Both rings install on the piston with the marking to the top.
Is all of the above correct?
Thanks John

The top ring is chrome-plated. That's the only way I could tell the difference.

You probably have a set of CB900F rings (same bore) with the oil ring being one piece?
In these kits the second ring has a circumferential notch. But the top ring is,like Dave says, plated also. This is a much easier ID than trying to see the taper, if there is one.
The notch on the 2nd ring in the 900 kit goes down.

Top Ring. Plated


Second Ring. Notched

I don't believe the rings are from the 900
The oil ring is 3 pieces.
The top ring isn't chrome plate, just plain cast iron (?). This is from memory, I'm not in the garage,
The second ring looks like a steel of some kind with the slight chamfer to the outer top edge as stated previously.
