I took apart a 74 h2b 750 motor a found out it had early 71-72 750 cylinders on the 74-75 cases 35 k range and cases were not drilled for the oil to run through the cylinders does this mean the bike was running on premix in the tank?

Presumably it ran on the H2-B system of oil into carbs, and the main bearings, but not into the intake port floor, as per early H2's.
