Reed Valve Gasket - 50cc 2-Stroke Minarelli 1PE40QMB

This Universal Parts reed valve gasket seals the interface between the engine case and the reed valve block on 50cc 2-stroke horizontal (Minarelli/Jog-style) engines. Made from high-compression fiber gasket paper resistant to fuel, oil, and heat, it provides a reliable airtight seal to prevent vacuum leaks and maintain correct air-fuel ratio. Replace at every reed valve service — these are single-use items.
