Exhaust Valve (OEM) GY6

Exhaust Valve for GY6 150cc Engines

This exhaust valve suits GY6 150cc engines and is an OEM-equivalent replacement. It controls airflow out of the combustion chamber, so it matters for how the engine breathes. If you have low compression or valve problems, this is the part to swap in. You can find it among other GY6 scooter parts for keeping your engine running well.

Signs It Needs Replacing
