Top to bottom.

Period correct.

Gonna get chopped.

Moyou approved.

This was the piston with the seized clip in the cb160 engine I was trying to use...

Damaged beyond repair = Crank swap.

+Bottom end rebuild.

+New oil seals.

What else should I do while I'm down there.....

Take your pick.

Left engine could easily be a runner.

I got the right engine from a guy after a bit of valve failure blew a piston.
