Athena Top-End Gasket Kit for 4-stroke engines, built for fast, reliable top-end refreshes before races or mid-season. Includes a premium MLSS head gasket plus multiple base gasket thicknesses to dial in compression.
Athena Top-End Gasket Kit is designed for pro, semi-pro and amateur riders who want a dependable way to freshen up an engine before a race or during the season. With a premium MLSS head gasket and multiple base gasket thickness options, you can restore sealing performance and fine-tune your setup for the fuel and compression level you want to run.
This kit helps you avoid leaks and maintain consistent performance after servicing your top end. The included base gaskets in different thicknesses make it easier to optimize compression—whether you prefer standard gas with stock compression or want to step up to race gas with higher compression.
Note: Kits do not include valve stem seals, rubber parts, shims, or other fiber gaskets.
