Engineered specifically for the legendary 2-stroke Yamaha YZ250, this complete hardware pack features everything needed to refresh a loose or leaking expansion chamber. Over time, high exhaust temperatures and aggressive track vibration degrade stock pipe seals and stretch out factory tension springs. Installing this **heavy-duty exhaust overhaul kit** maintains critical backpressure and stops messy oil spray from ruining your frame or engine cases.\u003c\/p\u003e\n\u003cp\u003ePrecision-sourced to deliver an absolute mechanical seal, every component matches factory tolerances perfectly for decades of vintage or late-90s YZ models. The kit includes high-durability rubber O-rings capable of resisting severe engine heat, alongside high-tension replacement pipe springs that firmly anchor your pipe to the cylinder spigot. Re-sealing your machine with this premium assembly keeps your exhaust system rigid and properly tuned, giving you clean throttle response right when you crack the gas.\u003c\/p\u003e\n\u003ch3\u003eTop Features: Vertex Exhaust Gasket Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete 2-Stroke Overhaul Package:\u003c\/strong\u003e Bundles application-specific O-rings, heavy-duty tension springs, washers, and necessary gaskets in one package.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEliminates Spooge and Leaks:\u003c\/strong\u003e Blocks unburnt oil and spent gases from escaping at the exhaust manifold to keep power output optimal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePremium Temperature Resistance:\u003c\/strong\u003e Advanced rubber compounds are specially formulated to endure constant expansion chamber heat without flattening out.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect Drop-In Fitment:\u003c\/strong\u003e Tailored directly to classic Yamaha engineering to guarantee a hassle-free, factory-level installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease review the detailed compatibility data below to ensure an exact fitment match for your motorcycle before finalizing your purchase.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eFitment List\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #e0e0e0; margin-top: 15px; margin-bottom: 15px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f7f7f7;\"\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eYear Range\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Brand\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Model \u0026amp; Sub-Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e1983-1998\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eYamaha\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eYZ250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Does this kit come with the pipe tension springs?\u003c\/strong\u003e\u003cbr\u003eA: Yes, this 2-stroke kit includes high-tension replacement springs along with the required high-temp exhaust O-rings and washers to complete the job.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Why is black oily sludge running out of my exhaust cylinder joint?\u003c\/strong\u003e\u003cbr\u003eA: That \"spooge\" means your internal pipe O-rings have flattened out or deteriorated from age and heat, allowing unburnt gas and carbon to leak out past the spigot.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I reuse old pipe springs if they aren't broken?\u003c\/strong\u003e\u003cbr\u003eA: It is highly discouraged. Old springs lose their structural tension over time due to heat cycles, allowing the expansion chamber to vibrate excessively and prematurely ovalize the cylinder spigot.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When swapping out your YZ250 exhaust gaskets, clean out the inside groove of the exhaust flange on the cylinder head with a wire brush or pick first to clear carbon buildup. Slide your new O-rings into place, then apply a slim bead of high-temperature copper RTV silicone directly over the new seals before seating the expansion chamber. This fills in any micro-pitting on vintage headers and guarantees a perfect, smoke-free lock.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \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\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/yamaha-yz250-and-yz250x-performance-parts-collection-at-moto-house-mx\"\u003eYamaha YZ250 \/ YZ250X Collection\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003ePremium Chemicals \u0026amp; Assembly Lubes\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
