What is the function of a choke on a motorcycle?
Function of a Motorcycle Choke A choke is used to help engines start. It’s function is to restrict (choke) air flow to the engine. The reduced air causes a rich fuel mixture which makes it easier for the bike to start.
Do you need a choke to start a motorcycle?
The choke is designed as an aide to help start your motorcycle. If you live in a hot climate, it might not be necessary to start your bike with the choke. In fact when it reaches around 75-80°F I rarely have to use the choke to start my Honda Shadow.
When to close the choke on a carbureted engine?
When doing a cold start, the choke should be closed to limit the amount of air going in. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up.
Why do you have to open the choke plate when starting a car?
When doing a cold start, the choke should be closed to limit the amount of air going in. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up. Once the engine has warmed up, a temperature sensing spring slowly opens the choke plate to allow the engine to breath fully.

Do you need to use choke every time you start your bike?
You do not need to use the choke every time you start your bike. After you get a feel for your bike, you’ll be able to tell by the temperature how much choke you need to use. Also the choke is not an on or off switch. Full-choke provides the maximum air restriction whereas half choke gives less air restriction.
Is there a choke on a fuel injected bike?
The answer is no, fuel injected bikes do not have a mechanical choke. A fuel injected bike does not have a carburetor. The air and fuel mixtures are determined by the Engine Control Unit (ECU). If the engine wants a rich fuel mixture for starting, it can automatically increase the amount of fuel injected into the cylinders.
What should I do if my choke does not work?
If the engine does not start when cranked over for a few seconds, release the key and press the accelerator to the floor one more time to evoke an additional accelerator pump shot. Most automatic chokes have a “clear flood” mode or “unloader” that is carburetor-linkage operated.
