Here is a carburetor for all of those "Honda Style" 4-stroke air cooled gas engines.
This is a PZ19 carburetor by KF (KunFu) Standard of Japan and is compatible with a variety of scooter, ATV, and dirt bike models, including the Honda Aero 50, Aero 80, Honda CRF50 dirt bikes, and Gyro scooters... AND all of the Honda clone Chinese made dirt bike and scooters of these models.
It is typically used on Honda style single cylinder engine sizes 50cc, 70cc, 90cc, and 110cc, but occasionally can be found on larger size engines.
But that's not all! Monster Scooter Parts gives you a choice of configurations for this carb. You can order it either with or without a
35mm Air Filter
