Complete ATHENA gasket kit (without lower engine oil seals) - Manufacturer reference: P400485850270
This gasket pouch is intended for engine refurbishment operations on off-road machines. This ATHENA kit contains 18 pieces and provides the essentials for reassembling the engine block after disassembly, explicitly excluding the lower engine oil seals. Designed for maintenance and restoration work, it prevents the reuse of worn gaskets during reassembly and facilitates a clean and durable seal between engine components.
This kit is aimed at mechanics and riders performing a complete engine overhaul: disassembly of casings, replacement of cover gaskets, and other sealing surfaces. Compatible with several cross models, it is particularly suitable for YAMAHA YZ 250 and WR 250 Z from the late 90s (see compatible references to confirm the year and displacement). For a complete repair, consider adding the lower engine oil seals if your intervention involves them.
