Honda CL160 Parts Catalog - The original Honda Parts Catalog for the CL160, published Nov. 1966.   The Parts Catalog shows how the parts fit together along with part numbers for each part.   It's up through page ninteen (of 75) right now.   I'll do more as I have time.   The CB is very similar.   For important stuff like the engine, they're exactly the same so this parts book applies as well.
