The Yoshimura muffler wash plug is an aftermarket exhaust wash plug designed for Yoshimura or compatible muffler systems fitted to Honda Ruckus motorcycles with a GY6 engine. It is used to facilitate internal muffler cleaning by allowing access through the outlet or a specific access port without requiring complete disassembly of the exhaust system.
Its function is to:
hermetically seal the wash port
allow controlled introduction of cleaning fluid
prevent fluid or gas leaks during washing
simplify internal muffler maintenance
Made with high-temperature resistant material and threads resistant to thermal and mechanical cycles, it provides a reliable access point for periodic cleaning.
