1971 Honda CB500K · Engine Buying guide
This engine selection brings routine oil-service parts together with gaskets, piston components, valves and cam-drive pieces. The useful first distinction is which assembly you are opening and what the chosen package actually supplies.
Stock-type paper oil filterFor the original-type filter assembly. O-rings, spring and washers are offered separately; a new element does not replace missing housing hardware.View part
Standard-size 56 mm piston kitSupplies one piston with rings, pin and a pair of clips. The listing specifies four kits for all four pistons; confirm the measured size first.View part
Athena overhaul gasket setA CB500K-specific overhaul gasket option. Check the listed set against the joints you will open; do not assume every seal or fastener is included.View part

An oil-filter element and a piston kit solve very different jobs. Start with the diagnosed repair, then add the seals and hardware needed for the assemblies being opened. Buying a broad assortment first can duplicate parts already supplied in a kit.
Open the relevant engine subcategory to compare piston packages, gasket coverage, valves or cam-drive pieces more closely. Choose by the actual part description and installed location, especially when similar names refer to different mechanical systems.
The Athena listing identifies an overhaul gasket set without an item-by-item contents list. The nine-piece oil-seal kit is a separate product. Confirm the particular seals and joints required before treating either package as a complete engine order.
The listed 56 mm kit rebuilds one piston and includes its rings, pin and clips. Its description specifies four kits for all four pistons. That quantity applies to this package; it does not establish the correct size for a previously rebuilt engine.
The paper element uses the factory-style housing. The chrome spin-on listing describes a conversion replacing that housing, its bolt and the paper element. Check which arrangement is installed before ordering spare filter-housing components.
