I just got a 40 year old motorcycle and I do not think it has been detailed since new. I have not cleaned a bike since college. (1970?)

What is recommended now for cleaning engine fins, Spoke wheels? Any suggestions will be appreciated.

This bike is identical to the one I had in college. It got destroyed in September of 1970. So 40 years later I am trying again. This bike has had a rough life for less than 20,000 miles of use.
