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!!
well on some dirtbikes it has it copied on the side of the front stock wich is the part of the frame just above the front mudgaurd (behind where a headlight would normally be) or you can also check the engine model number(usually locted directly under the carby on the motor) and compare it on the manufactuers website, if not then check the dirt bike manual
port out the cylinder head, replace the muffler, get a performance air filter, get a smaller sprocker for the rear wheel,and take off any electronics that you dont need.
The VIN number is not located on the engine, it is as a rule located on the front of the bike frame. The engine has the engine number, which is different from the frame or VIN number.
