Hey all!

So, now I'm rebuilding the top end of my '78 CB400TII. I have new piston rings, but I can't figure out which place to put the top two rings. One is plain silver, the other is black with the surface that contacts the cylinder silver.

The manual says that one of them should be tapered, but neither of them are.

Anyone know if the black ring is second or first???

Thanks in advance!

Silver is top ring, plain cast is second ring. Make sure the letter is facing up.
