Rebuild-ready sealing with compression-tuning options. The ATHENA Top-End Gasket Kit is designed for pro, semi-pro and amateur riders who want a dependable top-end refresh before a race or during the season. With a high-quality MLSS head gasket and multiple base gasket thicknesses, you can restore sealing confidence and dial in engine compression to match your fuel and performance goals.
Instead of reusing old gaskets or guessing thickness, this kit gives you clear options: keep stock compression for standard pump gas or raise compression for race fuel—helping you get consistent performance after service and reduce the risk of leaks.
Key features:
✅ Premium MLSS head gasket for strong, durable sealing
✅ Includes two or more base gaskets in different thicknesses to optimize compression ratio
✅ Lets you choose stock-gas/stock-compression or race-gas/higher-compression setup
Benefits of use:
🔹 Ideal for pre-race and mid-season engine freshening
🔹 Easier, more accurate compression setup without sourcing extra gaskets
🔹 Helps improve reliability by replacing critical top-end sealing surfaces
