Quick Answer: How To Use A Choke On A Motorcycle

When should I use choke on motorcycle?

When the engine is cold, the engine likes more petrol in the mixture than usual. 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.

How does a choke work on a motorcycle?

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.

Can you ride your motorcycle with the choke on?

No, it is definitely NOT o.k to ride with the choke on,the choke restricts the air supply to the engine when starting, to make the mixture petrol rich,as soon as the engine is warm enough to run without it should be closed.

How do you start a choke on a motorcycle?

Shortly after the engine fires, close the choke lever progressively and open the throttle slightly as the engine warms. As you ride, you may still need some choke for a short distance – but close the choke lever as soon as possible to achieve smooth running. Do not over-rev the motorcycle when it is warming up.

How long should I leave my choke on?

In short, leave the choke on as long as necessary, but once the motor is warmed and is idling well there is no need to keep the choke on.

Does choke open or closed carburetor?

The choke is a plate in the carburetor that opens and closes to allow more or less air into the engine. The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in.

Do you want the choke open or closed?

The choke is only used when starting a cold engine. When doing a cold start, the choke should be closed to limit the amount of air going in. Once the car has warmed up, if the choke does not open fully, the restriction in air may result in reduced power.

Does a choke let more air in?

A choke reduces the amount of air, keeping the fuel amount the same, making the mixture richer. An enrichener keeps the air the same, but increases the amount of fuel, making the mixture richer.

What happens if 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.

Why your motorcycle only runs on choke?

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.

Can you drive with the choke on?

It will not damage the engine at all. All that will happen is that it will run richer, thus using more fuel. If you did it for thousands of miles you’d probably end up with more deposits in the engine/exhaust, but even that is easy to sort.

Which way does the choke go?

Typically the “choke” is on when the choke lever is in the up position or when the choke lever is inline with the handle bars on your bike. Choke on means that the choke plate is covering the carb throat.

Do you hold the clutch in when starting a motorcycle?

It is always best practice to have your clutch pulled in whenever you initially start a bike. If you’re curious why, think about what happens when you don’t and you’re in any gear other than neutral: the motorcycle lurches forward (some more than others), sputters and dies.

Why does it take so long for my motorcycle to warm up?

Also, the motorcycle engine being air-cooled probably means it takes longer to come up to operating temperature. It’s in full cooling mode, so to speak, all the time. A water-cooled engine keeps the cooling system turned off until the engine is warm, so it can warm up faster.

Does an EFI engine have a choke?

As you might have guessed, there”s no choke butterfly attached to a multiport EFI throttle body–it”s all done with electronics, and common sense will guide you through.

Under which condition is choke is closed?

It avoids the excessive choking after the engine is reached the desired speed otherwise the exhaust will contain a considerable amount of unburned fuel. Operation of choke made to automatic also by using thermostat so that choke closed when engine is cold and choke open when engine is warm.
