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 .
