Description

Stage6 carburetor Dellorto PHVA 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.

PHVA carburetor

50cc scooter with Minarelli engine

The 17.5mm carburetor with auto choke is perfect for Minarelli engines such as the Yamaha Aerox or Malaguti F12.

Piaggio scooters

The carburetor also fits scooters with Piaggio engines such as Zip, Typhoon, NRG, but also Gilera Stalker, Runner and many others.

Universal carburetor 17.5

The PHVA is the most popular carburetor for entry-level tuning. It fits many models and vehicle types such as mopeds (requires the use of a rubber flange) or 50cc supermotos. If your bike does not have an automatic choke, you can supplement the 17.5 carburetor with a PHVA cable choke adapter or opt for a manual lever choke.

Adjusting the 17.5 STage6 carburetor

The main jet is size 80 and the pilot jet is size 38. Normally, there is no need to change these 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 the setup.

Note: To check whether the carburetor is set correctly, you should check the spark plug to prevent damage to the engine. The best way to do this is to watch our tutorial .

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
