What is the purpose of choke in motorcycle?

A choke valve/cable is designed to restrict the flow of air in the carburettor of an engine. This helps enrich the fuel-air mixture, improving the ability to start an engine in low temperature conditions.

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.

Why do I have to choke a warm engine?

The choke ‘chokes’ air going into the engine through the carburetor, effectively increasing the amount of fuel in the cylinder. In cold weather, this increases the chances of ignition. … In warm weather, a richer mix (more fuel in mix) is simply wastage of fuel as unburnt fuel is simply expelled.

Why does engine only run with choke on?

If a motorcycle or ATV only runs with the choke on, it’s because the richer “choke on” mixture is actually closer to the engine’s normal operating fuel mixture than the leaner “choke off” mixture. So when the choke is turned off, the engine gets too little fuel and too much air for it to run and it stalls.
