It does not include crankcase, transmission, or lower center-case seals.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Are the head gaskets in this kit reusable if I need to open up the cylinder head again?\u003c\/strong\u003e\u003cbr\u003eA: No, coated stainless steel head gaskets crush slightly upon initial torquing to form an absolute micro-seal. Reusing them significantly increases the risk of combustion leaks and coolant contamination.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Before laying down your new base and head gaskets, use a premium gasket scraper or chemical cleaner to ensure the aluminum mating decks on your YZ65 cylinder and crankcase are completely bare. Avoid using abrasive steel wool or wire brushes, as they can track tiny metallic swirls into the soft aluminum, which prevents the new gaskets from seating flawlessly and leads to micro-leaks under high compression.\u003c\/p\u003e\n\u003ch3\u003eRecommended Pairings:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz65\"\u003eYamaha YZ65 Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-2-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eYamaha 2-Stroke Performance Parts\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
