908305 Top end gasket kit

Rebuilding the top end of a classic thumper requires quality seals, and this Athena top end gasket kit is designed to provide a leak-free finish. This kit fits 1979 to 1982 Honda XL500 models and 1979 to 1982 XR500R models. It includes every gasket needed from the base gasket up, including all rubber seals, valve cover gaskets, o-rings, and valve stem seals. To ensure a superior seal under high heat, Athena applies a high-temperature blue silicon beading to the most critical flat gaskets. This kit is engineered to meet original equipment standards, making it a reliable choice for restoring compression and performance to your 500cc single-cylinder engine. Sold as a complete kit for a professional-grade top-end overhaul.
