Should the throttle be turned off or on when the motorcycle is running normally?

Of course, the damper for normal driving is open. If it is closed, it will cause air to enter and it will be closed. Air gate, also called choke or throttle, as its name implies, is a device to prevent fresh air from entering the carburetor; When you close the throttle, the amount of air inhaled is reduced, and the concentration of gasoline is high. Gasoline with high concentration is naturally easy to ignite. Therefore, when starting in cold car, cold weather or windy weather, it is necessary to close the air door to reduce the air intake, which makes it easier to start by ignition.
