Choose the service location first, then identify the pieces disturbed by that repair. Individual filters and piston kits have different coverage from gasket and seal sets; counting those contents prevents an incomplete or duplicated order.

A standard piston kit supplies one piston, rings, pin and two clips. The seal kit supplies nine listed engine seals, while a paper filter is one service element. Count each package according to the repair plan; a shared engine application does not turn an individual component into a complete rebuild order.
Compare the Athena top-end and overhaul sets with the actual joints being opened. Their names describe repair scope, but do not establish an exhaustive list of every oil seal or O-ring. Check the set contents first, then add separately needed seals rather than assuming either a missing item or a duplicate purchase.
One kit covers one standard 58.5 mm piston position, including rings, pin and two clips. Replacing all four needs four suitable kits. Have the measured cylinders and fitted piston size checked before confirming that standard-size order.
Identify the leaking joint, inspect its mating surfaces and compare the separate gasket with the installed cover. A shaft seal or cap O-ring is a different component; choose it only when that location is part of the repair.
The primary-drive rubbers cushion an internal drive assembly and have a different function from cam-chain supports. Identify the actual system before ordering; neither internal primary dampers nor cam-tensioner pieces replace rear-wheel chain adjustment hardware.
