Yamaha - Reed Valve Assembly - Intake Air Control System - 6E8-13610-01-00

Overview

When a two-stroke isn’t running clean, I always think about the reeds early on. I’ve seen engines with rough idle or sluggish throttle come right back to life after replacing a worn reed valve assembly. This is what controls how air and fuel enter the motor, so it has to react quickly and seal tight. When it’s working right, the engine feels crisp, responsive, and easy to start.

Key Features
