Stage6 PHBG DS 21mm Carburetor

Stage6 21mm PHBG Carburetor
DellOrto carburetor optimized by Stage6 for 50cc scooters, 50cc motorcycles, and mopeds. 

When performing engine tuning, it is advisable to replace the original carburetor with a larger one, both to improve performance and to maintain reliability. 

PHBG Carburetor
This is a 21mm DellOrto PHBG carburetor offered by Stage6. This universal manual choke carburetor is compatible with many two-wheelers, including scooters, 50cc motorcycles, mopeds, vintage Vespas, and other vehicles equipped with a 2-stroke engine. 

The choke is manual, so you can choose to mount either a manual cable choke or replace it with a manual pull choke. 

Tuning the Stage6 21 Carburetor
As a general rule, it is advisable to also order an additional jet kit (5mm diameter) in order to adjust the settings to your engine. 

Note: to check if the carburetor is properly tuned, you must look at the color of the spark plug to avoid damaging the engine. For this, consult our tutorial.
