If you’re having trouble starting your motorcycle in the morning, it’s usually because of the fuel. The gas might not be flowing properly or hasn’t reached the engine yet. Even if you’ve turned the engine on, if the fuel isn’t burning, the engine won’t start.
The manufacturers have thought of this problem and created a tool called the “choke.” You’ll usually find the choke lever on the left side of the motor handle.

To use the choke lever, just pull it if you’re having trouble starting the engine at certain times, like in the morning or at night, or in cold weather.
