I forgot to include pictures. To be honest I didn't take any pics of the assembly process as I just wanted to get it done. So here's some take apart pics...

Engine in the frame with the valve inspection cover removed. As you can just barely see it's a push rod engine. The means the cam is located in the bottom end and the valves are activated by levers that are pushed up by the rods on the far side of the engine.

Cylinder head, with one valve partially removed.

Here's the cylinder head removed. All that black stuff is built up carbon - these are safety council bikes so they spend forever idling, and never hit highway speeds. That was burned on black crap about 1/5" thick that I had to literally chip off. Remember to wind your bike out a bit sometimes.

Label everything explicitly.

Valve parts.

Exhaust valve that's carboned to HELL!

Here you see the underside of the rocker arms. Those worn pad looking things are what ride on the camshaft. As the cam passes they are lifted up and push a rod that activates the valve at the top of the engine.

Yes, I actually did all the work.

Here's the clutch

Here's the insides of a clutch.
