Where is the normal position of the motorcycle choke?
2 Answers
Motorcycle chokes are generally fully open, which is the lowest position. They only need to be closed to adjust the air-fuel mixture when starting is difficult in winter. During normal operation after starting, the choke must be fully open; otherwise, it will increase fuel consumption and damage the engine. The usual position is the lowest, with the least air intake at the top position and moderate intake in the middle. In other words, the top position provides the richest air-fuel mixture, the middle position is less rich, and the lowest position is for normal use. Additional information: Choke definition: The choke is a unique device in carburetor-type gasoline engines, used to adjust the air-fuel mixture concentration for easier starting. Under normal circumstances, it should be kept in the open position. Choke classification: The choke, also known as the air choke, is used to regulate the amount of air entering the engine. There are two principles of choke operation: one reduces the amount of air entering, and the other increases the amount of fuel entering. Both aim to enrich the air-fuel mixture, making it easier to start a cold engine.
The choke on a motorcycle should normally be in the closed position, which is its standard operating state. Having ridden motorcycles for twenty years, I often only need to open it to enrich the fuel mixture during cold starts. However, it must be closed immediately after starting; otherwise, the engine may experience shaking or excessive fuel consumption. Once, I forgot to close it and felt the engine struggling with black smoke coming out, which was quite annoying. Now, I've developed a habit of checking the position of the small lever or button on the handlebar after starting to ensure it's in the 'off' position. The location varies by model—some are on the right side of the handlebar or near the control panel—but it should always be closed during normal operation. I recommend checking it every time you ride to prevent minor issues from becoming major problems, especially since beginners might overlook this.
