§ 02 / About this part
What it is
Athena top-end gasket kit to fit the Yamaha WR250, model years 1991–1997; Yamaha WR250Z, model years 1991–1997; and Yamaha YZ250, model years 1988–1996.
Seal the top-end of your bike correctly during every piston change or cylinder inspection. This kit includes the head, base, and exhaust seals required to maintain primary compression. These components replace heat-cycled parts that degrade over a race season. Fitment matches OEM specifications for your specific bore and stroke. Ensure all mating surfaces are scraped clean and degreased before you install the new parts. For four-stroke builds, seating the valve stem seals correctly prevents oil blow-by. This is a standard workshop requirement to prevent coolant migration and pressure loss in the combustion chamber.
