To set the carburetor on the Hero Honda CD 100 bike, locate the set screw attached to the carburetor. Start the bike and using a screwdriver, turn the screw until the bike runs smoothly. This may take a few tries to make sure the screw is getting turned the right way.
The black Phillips head screw on the rear of the carburetor adjusts the airflow. You need to have it about 4 full turns into the hole and that's factory. To set the carburetor, just continue to screw in the air screw until the bike runs properly. In your climate, you will hear and feel the bike get smoother as the carburetor gets to the proper setting. Try it out and have a blast!!
The idle air is adjusted via a screw on the linkage. The gas flow is automatically set by the computer via the vari-jet inside the carburetor.
