My bike is going back together with a donor engine. I want to save the matching number engine case and a few other parts. the engine is mostly disassembled. I was thinking I should clean the parts (at least get all the mud dauber nests out of them), coat them with light oil, and wrap them, but I really have no clue. Any suggestions?

Should I try to remove the camshaft (I think) bearing that is in the rear of the engine case? (If so, heat or cold, and a bearing puller?) Or just oil it?

Any other suggestions to protect these parts from further corrosion?

Disclaimer -- I only know

Disclaimer -- I only know what some wrong storage "techniques" are from experience, but it sounds to me like you're on the right track. You could use light oil, or spray with WD-40. Once oiled, you could keep each piece in a plastic bag.

To get the rear cam bearing out, use a torch to heat the area behind it. There's a bump you can see that is the back of the blind hole, and that, and its immediate surroundings, is the area to work on. You want to heat it to 250-350F. If you don't have an infrared thermometer, a rough estimate is that spit sizzles and dances. The bearing should just fall out... If it doesn't, you'll have to try to get a blind puller in there.
