Why is it difficult to start a motorbike in cold weather?

The weather in the North has turned cold, motorbikes left overnight often have difficulty starting, sometimes affecting the user's life. However, if the cause is clearly understood, it is not difficult for the driver to fix it.

Difficulty starting often occurs on manual transmission vehicles using carburetors. The cause is due to low temperatures, which reduce the evaporation of fuel, resulting in an insufficiently dense gasoline-air mixture. On cold and drizzly days, high humidity causes the air in the engine to condense into small water droplets in the carburetor and fuel line. The amount of air needed to start the vehicle is lacking, causing difficulty starting.

More importantly, the condensed water will clog the parts in the fuel line or affect the spark plug tip and create carbon deposits there.

Fixing this problem is not difficult. To keep the car running smoothly, regular maintenance is required. Users need to focus on cleaning the spark plugs and carburetors, along with adjusting the carburetors, which also requires experienced mechanics to adjust them properly. This will also help the engine run durably and optimize fuel consumption.

In addition, there are a few small tricks to help the vehicle start easier. For common manual transmission vehicles, the simplest is to open the throttle - this part is usually located right below the horn and often has the effect of increasing the amount of gasoline to make the gasoline-air mixture more concentrated. When the throttle is opened, do not turn the throttle because it will increase the amount of air.

Or you can press the foot starter a few times to let the carburetor suck more fuel down, then press the starter button. Note that you should not hold the starter button for more than 3 seconds because it will damage the battery. If the car still does not start after 3 seconds, you need to wait 10 to 20 seconds before restarting.

For scooters that often use electric throttle, before starting the engine, turn on the ignition and turn the throttle all the way down a few times to push more of the gasoline-air mixture into the combustion chamber.

Once the engine starts, let the vehicle idle, you can increase the throttle slightly to maintain the running state for a few minutes, warm up the engine, then you can close the lever back to its original position. When the vehicle has started stably, you can let the vehicle run.
