Ruttly I'll have to cheer for ya for taking on such a task !
I went and bought two - new manufacture - "Retro Bikes" instead of getting an original to restore.
So
At least your more ambitious than I am .

I did do my own valve adjustment on the RE650 today , it took a whole two and a half hours , and 30 minutes on U-tube ! I had to watch two different ones just to be sure they agreed on what to do !

Two cylinders / 4 valves per cylinder , but getting to the Valve cover took most of the time.
