I did a little search for your pistons. They're available in parts (i.e. piston, rings, etc) or as reproduction kits for what seem to be reasonable prices. Have a look through some of these.

These are still easy to find. David Silver Spares (https://www.davidsilverspares.com/CB77-305) has some listed but are out of stock. Something to keep in mind: There was a major change in the front fork and several changes in the steering stem over the years of production. I don't know how this affe...

I'll bet it made assembly easier though. ;-) An ohmmeter may be all you need. They often fail by shorting to ground so if the resistance between the...

Things like this are often hard to diagnose but here's one idea. The throttle cable needs to be really clean and free to move. If it sticks and holds the slide a bit above the idle speed screw it can slowly move and drop the idle speed. WD-40 is a convenient cleaner to inject at the top and catch at...

My limited experience (N=1) tells me that you should have an easy time. I degreased the block thoroughly so as not to fill my oven and house with oil fumes. I heated the oven to 175℃ (350℉) and left the block in for about 1/2 hour. Less time would probably have been enough. Taking it to my workbench...

To answer your question, yes, you should see much more resistance on the secondary coil if you are getting any spark at all. And, if the right side was giving a good spark but the left wasn't, it seems to me that there would have to be a problem with the left side connector, wire, cap or spark plug....
