Vertex Exhaust Gasket Kit 823141 — Yamaha YZ250 1983-1998

Product Description

Stop power-robbing exhaust leaks and restore factory compression sealing with the Vertex 823141 Exhaust Gasket Kit. 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.

Precision-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.

Frequently Asked Questions

Q: Does this kit come with the pipe tension springs?
A: 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.

Q: Why is black oily sludge running out of my exhaust cylinder joint?
A: 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.

Q: Can I reuse old pipe springs if they aren't broken?
A: 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.

Expert Pro-Tip: 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.
