Where is the normal position of the motorcycle choke?
4 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.
The motorcycle choke is normally in the 'off' position, and you must never leave it on after starting. I enjoy riding motorcycles for leisure, and I use the choke for cold starts, but I always turn it off within three seconds after ignition because leaving it on disrupts airflow and causes unstable engine operation. It's usually a small lever or knob located on the right-hand control cluster. If you forget to turn it off, the engine may vibrate more intensely, fuel consumption can spike, and I've even experienced cases where the spark plug got fouled. During maintenance, you can gently push it to confirm it returns to its original position. In short, the normal position is 'off' when not needed—simple but crucial.
The motorcycle choke should normally be closed. It must be shut off after starting, otherwise it will make the fuel mixture too rich, causing the engine sound to become rough or damaging parts. It is mostly located in the handlebar control area and is something that can be pushed. During maintenance, I usually check if it returns smoothly. Leaving it open will also increase exhaust emissions. Turning it off promptly is the right way to go.
