When Should the Choke Be Used? The choke should only be used when starting and warming up your motorcycle. You can leave the choke engaged while the engine warms up to operating temperature. It may be necessary to leave the choke on while you ride for the first mile or so to warm the bike up.
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.
Is it OK to ride motorcycle with 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. … Most older bikes with carbs would not react well to running with a choke on.
When should the choke be open?
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. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up.
How long should I 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.
How does choke work on 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.
How cold is too cold for a motorcycle?
So how cold is too cold to ride a motorcycle? It is not recommended to ride a motorcycle when the temperature is below freezing (32°F or 0°C). Ice will form at these temperatures and motorcycles are more susceptible to ice since they are smaller vehicles.
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.
Why does my motorcycle die when I turn the choke off?
However, you start it up on choke and everything is fine until you turn the choke off, and the engine dies. What gives? This is a classic symptom of a partially or fully clogged pilot jet. Fuel goes bad after time, and the first circuit/jet to clog with varnished up fuel is the pilot jet.
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 full choke open or closed?
FULL Choke means the choke is closed. This seals off the carburetor’s air supply in order to create a richer fuel mixture needed to start a cold engine. Move the choke back to RUN once the engine warms up.
What can go wrong with a carburetor?
Carburetor Problems and Solutions
|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|
Should the choke be up or down?
We would say that the “choke” is on or closed. This restriction of air flow reduces the amount of air available for combustion which means that the air fuel mixture is very rich. … The “choke” is off when the choke lever is down or when the choke lever is facing you if your choke is a handle bar mount.
How long should you let a motorcycle warm up?
How long should you warm up a motorcycle? About one minute is plenty of time to allow the piston and other parts to gradually expand and ensure good oil circulation to the upper end.
Is it bad to drive with choke on?
3 Answers. 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.
Do you have to choke engine to keep running?
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.
