EGR/PAIR Emissions Block Off Plate for 50cc and 125cc-150cc Engines
This emissions block off plate is designed for use with 50cc 139QMB and 125cc-150cc GY6 4-stroke engines. It effectively seals off the emissions port in the cylinder head, particularly useful if the emissions system is malfunctioning or when upgrading to an aftermarket exhaust system. This component is one of the simplest modifications to make at home, allowing for improved engine performance.
Functionality and Benefits
The EGR/PAIR emissions block off plate helps eliminate potential leaks from the emissions system, which can hinder engine efficiency. By blocking these ports, you can improve the performance of your scooter or moped. This modification is often necessary when installing a new exhaust system, helping to create a more streamlined setup.
Installation Considerations
When installing this block off plate, it may be necessary to adjust the carburetor's vacuum hoses or convert to a single vacuum intake configuration. Depending on your specific model, you might also need to use a non-emissions head cover. This part is intended solely for off-road use and is not suitable for public roads.
