The Sunworld PE 28mm (4T) carburetor is an aftermarket intake component designed for GY6 4-stroke engines, including Honda Ruckus GY6 setups. It manages the formation and distribution of the air/fuel mixture to the combustion chamber, with a 28mm body allowing for greater airflow than smaller carburetors while maintaining efficient flow velocity.
The PE (Progressive Enlargement) design promotes internal flow homogeneity, optimized fuel atomization, and improved engine response across a wide RPM range. The 28mm size is a good compromise for GY6 engines ranging from 125cc to 180cc with increased performance requirements or intake/exhaust modifications.
The carburetor comes with a standard set of jets and basic parts, but fine-tuning the main and pilot jets is highly recommended depending on the specific setup.
