I want to learn more about what features enable a motor to be more efficient so I can make an informed decision.

Is there information available can make this possible?
Well, some basic things you can look for are an undersquare engine, fuel injection, and a higher compression ratio. Sounds like whatever bike you were looking at has a really old engine design. Even the 1960s Honda 50 had an overhead cam. If you end up getting a bike with a carb, make sure the carb is tuned right and not just dumping fuel. You should be able to achieve great fuel economy even with a carb.
