Dellorto PHBG 21 Carburetor

Dell’Orto PHBG 21 mm DS carburetor for 50cc scooters, motorcycles and mopeds.
When upgrading your engine with a 50cc or 70cc Sport / Racing cylinder, it is highly recommended to replace the stock carburetor with a larger one to ensure optimal performance.

The carburetor is delivered with a size 92 main jet. We recommend ordering additional 5 mm jets to fine-tune the carburetion for your specific setup.
