What are the essentials you clean or upgrade on a old motorcycle??

[z3r0s0n1k]

Inherited a 1972 Honda CB500, hasn't been started for 12yrs. Been stored inside since 1989. Motor rebuilt and overhauled, have front clip (fork,handlebars,tire,susp.) from a 74' 750?, no berring. All i know bout it. Seems pretty logical, but I'm not familiar with motorcycles yet. Wanted a experienced opinion(s) before I tore apart the motor lol. Any advice would be appreciated, Thank you.

the cost to restore it will exceed the cost of a new bike "IF" you can get parts for it.
I say either sell it of junk it.
