125 The EFI motorcycle is turned off in rainy days and left to stand for 15 minutes. What is the reason?

125' s EFI motorcycle suddenly turned off when driving in rainy days, and then failed to continue to turn off the throttle. This problem is basically caused by the abnormal high-voltage electricity caused by the water inflow of ignition system parts or ignition control system parts, sensors and wiring plugs. In addition, in rainy days, the water in the fuel tank and the water in the air filter will also cause the quality of the mixed gas to deteriorate, resulting in poor combustion, easy flameout and inability to refuel the valve.

Different from automobiles, many switches, electrical components, lines and plugs of motorcycles are exposed, and these components may get wet in rainy days, which will affect the normal operation of the ignition system and weaken the high-voltage electricity, resulting in the motorcycle engine being unable to ignite and operate normally. Some of this happens by accident, some of these parts are not well assembled or waterproof measures are not in place. It's not easy to solve, because everything is normal when this doesn't happen at ordinary times, and there is no problem even throwing water on the car. If you want to repair, you can only check these related parts one by one, and then wait until it rains to see the effect.

In addition, when the motorcycle is driving in rainy days, rainwater may also enter the fuel tank and nozzle through the fuel tank cover and throttle line, and gasoline will affect the combustion, and then it will return to normal after the water is removed. The air is humid in rainy days, and inhaling too humid air may also affect the quality and combustion effect of the mixture. Moreover, if the air filter element enters the water, it will also cause the mixture to be too thick, and it will also cause the hot car not to add the throttle to stall.
