Product Description:
Up for sale is a brand-new, Genuine Yamaha OEM YPVS (Yamaha Power Valve System) Housing Gasket, part number 1LX-11993-01-00. This is an authentic factory replacement component, not an inferior aftermarket reproduction.

It features the exact factory 4-bolt hole configuration designed to prevent exhaust leaks, maintain proper engine compression, and ensure your classic YZ runs at peak performance.
