Is it bad to leave the choke on?
Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. This is also bad for the environment. The choke is mainly used during winter to help with starting. The engine needs its fuel to be vaporised in order to burn it.
What is use of choke in Activa?
The choke restricts (‘chokes’) the airflow to the carburettor to make the fuel-air mix richer.
When should I use choke on a scooter?
A cold engine won’t vaporise the fuel as well as it would in warmer conditions, so the choke helps enrich the mixture (either by adding in more fuel or cutting out airflow) to increase the amount of combustible vapour available to start the engine.
What happens if we drive bike with choke on?
When choke is applied the resulting air fuel mixture would be 14:2 or 14:3, which easily ignites and engine starts quickly. Once the engine starts and engine is warm enough you need to disengage choke as its not fuel efficient.
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.
Should the choke be 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.
How does Activa start in cold?
10 Tips To Handle Cold Starting Trouble
- Go for a Kick.
- Providing Choke.
- Switch to a Low Grade Engine Oil.
- Tune Engine for Rich Mixture.
- Clean Spark Plugs.
- Do Not Stress the Battery.
- Let Engine Idle Before Moving.
- Cover Bike with Insulating Material.
Why will my bike only run 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.
Should the choke be in or out?
The choke is located before the throttle, and manages the total amount of air going 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.
How do you know if the choke is on or off?
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. Choke off means that the choke plate is not covering the carb throat.
