The weather in Suzuki, Shaanxi

When the weather is cold, the cold motorcycle will fall to varying degrees. When the cold car starts, you should pull up the air door directly, and don't wait for multiple starts before pulling up the air door. After you start, you should warm up for a while. Don't pull the throttle back in a hurry. You should continue to pull the throttle to warm up until the engine temperature rises and the operation is stable. You can also pull the throttle for a while and then send it back gradually. At present, in order to meet the environmental protection standard of exhaust gas, the fuel supply of carburetor is limited, which has a certain adverse effect on the performance of cold car.

If the situation is too serious, or the correct starting and preheating methods are not enough, you can check whether the mixing ratio of the carburetor is too thin, whether the air door is not thickened properly, whether the spark plug is broken, whether the valve clearance is too small or closed incorrectly, and whether the hoses such as the intake pipe are slightly leaked.
