This kit provides the essential top-end sealing components needed for a reliable engine rebuild while supporting performance-focused applications.\u003cbr\u003eThe kit includes a premium MLSS head gasket and multiple high-quality base gaskets in different thicknesses. These gasket options allow riders and engine builders to fine-tune the engine’s compression ratio according to the intended fuel and performance setup. Use the appropriate base gasket for stock compression with standard pump gas, or select a different thickness when configuring the engine for higher compression and race fuel.\u003cbr\u003eAthena manufactures this kit with attention to fit, sealing performance, and application-specific compatibility. The P400210600221 kit is a practical choice for maintaining consistent combustion sealing during demanding riding conditions, whether preparing a race bike, completing midseason maintenance, or rebuilding the top end. Verify the application and engine specifications before installation to ensure the correct gasket configuration.\u003cbr\u003eThis Athena top end gasket kit does not include valve stem seals, rubber components, shims, or other fiber gaskets. Additional replacement parts may be required to complete the installation, depending on the condition of the engine and the scope of the rebuild.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eBrand: Athena\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: P400210600221\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApplication: Designed for compatible Honda engine top-end service\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRider Level: Suitable for professional, semi-professional, and amateur riders\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHead Gasket: Includes a premium MLSS head gasket\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBase Gaskets: Includes multiple thickness options for compression-ratio adjustment\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFuel Flexibility: Supports stock-compression setups with standard gas or higher-compression setups with race gas\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eExclusions: Does not include valve stem seals, rubber parts, shims, or other fiber gaskets\u003c\/li\u003e\u003c\/ul\u003e\r\n\u003cp\u003eShips from Parts Unlimited.\u003c\/p\u003e","brand":"Athena","offers":[{"title":"Default Title","offer_id":60117763653918,"sku":"P400210600221","price":80.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1091\/7884\/7518\/files\/79095.png?v=1791112381","url":"https:\/\/shoplepier.com\/products\/athena-p400210600221-top-end-gasket-kit-for-honda","provider":"LEPIER POWERSPORTS","version":"1.0","type":"link"}
