6 ways to identify a motorbike that "eats" gas

1. Difficult start

The most easily recognizable sign when the car consumes a lot of gas is that it is difficult to start each time it is started. Due to the lack of gas supply, it is often difficult to start; At the same time, when driving on the road, the driver always feels that the car is "out of breath" and does not run as well as usual.

When accelerating or decelerating, there is a “gurgling” sound that makes the car weak. This is also a sign that the car is having “gasoline drinking disease”.

2.Exhaust smoke

When the vehicle consumes too much fuel, the exhaust pipe emits black smoke due to excess fuel in the combustion chamber. This causes waste and serious environmental air pollution.

If white smoke appears from the exhaust pipe, it means the engine has a leaky piston, which is also the main cause of fuel consumption.

For a motorbike operating normally, the naked eye will not be able to see smoke from the exhaust pipe.

3.Observe the spark plug

Another way to tell is to look at the condition of the spark plug. If you remove the spark plug and see that it is burnt black, it means that the car is wasting fuel. Normally, the faster the car runs, the redder the ceramic and spark plug pins become. However, if the car is wasting fuel due to excess fuel, the spark plug will still be black no matter how fast it runs.

4.Check carburetor temperature

A carburetor that feels cold and has or doesn't have condensation is a fuel-consuming vehicle.

Have you ever wondered why the carburetor is cold to the touch and sweats (fogs)? The principle of thermodynamics: evaporating liquid absorbs heat. The carburetor has excess gasoline, the evaporating gasoline absorbs heat from the tank and cools down the cold carburetor, even condensing if the humidity is high. Cold carburetor => vehicle consumes more gasoline.

5.Check air filter

This part is usually mounted in front of the carburetor of each vehicle, right behind the fender. Its task is to prevent dirty air from entering the carburetor and the motorbike engine. The reason why motorbikes consume a lot of gas is partly due to the air filter not being cleaned and replaced for a long time.

According to the manufacturer's recommendation, the vehicle's air filter should be replaced every 1,000 km of the vehicle to ensure overall performance.

6.Compare km/liter of gasoline consumption

This is the simplest and fastest way that everyone can apply. If you are someone who goes to work at a fixed time and travels the same distance every day, it will be easy to recognize the situation of the car consuming fuel. For example, when you first bought a car, you filled it with 1 liter of gas and it ran for 3 days, but now you fill it with 1 liter of gas but it only runs for 1 or 2 days...

To be more accurate, you can save the odometer reading to see how far 1 liter of gasoline can go (note to fill up by the liter because the price of gasoline may have increased, so when filling up at the same price, the amount of gasoline will be less than before).
