The Sunworld PE 26mm (4-stroke) carburetor is an aftermarket intake component designed for GY6 4-stroke engines, including those found in the Honda Ruckus GY6.
This carburetor manages the air/fuel mixture delivered to the engine, ensuring a smooth, responsive distribution across a wide RPM range. The 26mm body width provides a balance between airflow and flow velocity, making it particularly suitable for 125cc to 180cc engines with stock or slightly modified configurations.
The PE (Progressive Enlargement, constant venturi body) design is a common architecture in 4-stroke motorcycle/scooter carburetors, offering:
a smooth throttle response
more consistent combustion
efficient atomization
accessible adjustment for optimal performance
This carburetor comes with a basic set of jets, but fine-tuning the jets (main, pilot) is recommended depending on the intake, exhaust, altitude, and type of use.
