one on left needs dentures

Light snow fell all day, as yesterday. The cb450 engine was the focus of the day. I worked out what I think is a way to feed the cam chain(some say it's the longest of any motorcycle) through the engine with wires as I put the head on...and afterwards to time it correctly. The piston rings were installed and I found a cam chain tensioner from a cb500t in my collection of parts- in much better shape than my original.
