Stage6 carburetor Dellorto PHBN 17,5

Dell'Orto carburetor from Stage6 for 50cc scooters, motorcycles and mopeds.

Whenever you increase performance, the original carburetor should be replaced with a larger one in order to optimally support the new setup and achieve better acceleration and higher top speed.

PHBN carburetor

This is a 17.5mm PHBN Dellorto carburetor from Stage6. The 17.5mm carburetor with manual choke is the perfect fit for Minarelli engines (such as Yamaha Aerox, Yamaha Jog or Malaguti F12), but can also be used on other scooters, motorcycles or mopeds.

Adjusting the carburetor

The main jet is size 90, the secondary jet 34. Normally there is no need to change the jets, as the carburetor runs very smoothly ex works. You can, of course, order additional carburetor jets (6mm) in order to adjust the carburetor setting optimally to your setup.

Note: To check whether the carburetor is adjusted correctly, you should check the spark plug to prevent damage to the engine. Take a look at our tutorial on this.
