Your question: How do you start a choke on a motorcycle?

How do I know if my choke is open or closed?

How do you start a choke engine?

A typical starting procedure for an engine with a choke might be:

  1. Close the choke (usually on carburetor).
  2. Set the throttle control (if any) to the START or HIGH position.
  3. Pull the starter cord once or twice (if it doesn’t start on the first one).
  4. If it still doesn’t start, open the choke half way.

What is the choke lever on a motorcycle?

On a motorcycle, a choke valve is likely to be a pulling lever either directly attached to the carburettor or indirectly attached to the carburettor via a cable. … Once the engine is in use, and naturally warms up, the choke valve can be closed, to reduce additional fuel being used.

How do you adjust the choke on a carburetor?

When Setting An Automatic Choke the vehicle must be cold (hasn’t run for 4-5 hours): Remove the air cleaner assembly and depress the throttle twice. The first throttle press is to set the choke plate, and the second is to give the motor a shot of fuel. The choke blade should be completely closed at this point.

What happens if the choke is left on?

Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. … The engine needs its fuel to be vaporised in order to burn it. This is done by the carburettor where the fuel is mixed with clean air coming from the air filter, and sent into the pistons to be ignited.

Is it bad to run an engine with the choke on?

Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine. … Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.

How long should you leave the choke on?

The choke usually “chokes” the air supply into the engine so it gets more petrol than usual. Hence it’s name. You should start the bike from cold with half or full choke depending on how cold it is. After 30 seconds is usually enough for most bikes.

What does pulling the choke do?

By restricting the flow of air into the throat of the carburetor, the choke valve reduces the pressure inside the throat, which causes a proportionally-greater amount of fuel to be pushed from the main jet into the combustion chamber during cold-running operation.

When should I use choke on motorcycle?

The choke restricts airflow into the engine, making it easier to start and run when cold. Once the engine is warm, unchoke it. The choke chokes airflow to the carb, which means fuel-air ratio to the engine is richer in fuel.

What can go wrong with a carburetor?

Carburetor Problems and Solutions

PROBLEM POSSIBLE SOLUTION
Carburetor floods Engine starves for fuel at high speed (leans out) Check inlet needle and seat for condition and proper installation
Carburtor leaks Engine overspeeds Idle speed is excessive Check sealing of welch plugs, caps, plugs and gaskets

How does an electric choke work on a carburetor?

Automatically – An automatic choke uses a metal spring to open and close the choke plate. The spring is wound in a housing and attached to the choke linkage on one end. As the engine warms up, it warms the metal spring. … Electric Choke – An electric choke uses electricity to warm the spring and gradually open the choke.

Which position is choke on?

Additionally, what is choke position? Similar to the throttle, the choke plate rotates from a horizontal to vertical position to open up the passageway and allow more air to get by. The choke is located before the throttle, and manages the total amount of air going into the engine.
