    Worth restoring

    Given a 1977 CB750K Stored in garage hasnít run since 1987. compression 135 to 145. Carburetor must be rebuilt. New battery everything appears to work. Canít figure out why after changing oil the tank oil wonít go into engine. Want any wisdom on the possible new project

    Its a dry sump engine. The oil is held in the tank and circulated when running. only a couple of cups of oil should be in the engine pan. Guess I am not sure if I am understanding your question though so ....

    Shouldnt be anything in the engine just by filling the tank...it doesnt drain from the tank to the engine. When you drained the oil did you drain the tank as well? If the tank is empty it should hold the 3 qts, if you are only getting 2 qts in then you didnt get the tank drained.
