Description

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.

Notes and Safety

Carburetor for scooters, motorcycles and mopeds

The smooth operation and optimum power output of your scooter, motorcycle or moped depends, among other things, on the carburetor, whose job is to create the right mixture of air and gasoline.

How the carburetor works

When the rider operates the throttle, the carburetor slide moves upwards, increasing the air flow that is sucked in through the air filter. The carburetor then mixes this air with petrol, creating a combustible mixture. This mixture is fed into the cylinder through the intake manifold and the reed valve.

The carburetor is equipped with jets to adjust the ratio of fuel and air and thus ensure an optimum air-fuel ratio. It is important that you adjust the carburetor settings to the setup of your engine.

Adjusting the Carburetor

Proper carburetor adjustment is critical for optimal engine operation and durability. Depending on the type of air filter, cylinder and exhaust of your setup, you will need to readjust main and pilot jets. To check the correct operation of the carburetor, you can refer to the color of the spark plug:

White spark plug = too lean
Black spark plug = too rich
Brown spark plug = optimal setting
