So I have my bike in pieces and am wondering what to do next. The engine is out, I have a gasket kit on the ready but am wondering about other jobs that I should while it is apart. History: 70,000 miles 1974 r75/6. The bike sat for 5 years. previous owner said it was well mantained... who knows

Questions:
How do I know if the timing chain needs to be replaced? Can I know this without taking the whole engine apart?

How do I know if the cam shaft bearing needs to be replaced? Can I know this without taking the whole engine apart?

The cylinders look really shiny and are free of any visible imperfections (this is my first time ever seeing a cylinder, but I am amazed by how clean they are) So should I do anything to the rings or the pistons? i.e. hone and replace?

I have attached a pic of one of the cylinders...if it helps.

Thanks a lot for the help. This is the link to my thread. Thanks again!
