Why Does a Underbone Motorcycle Frequently Stall on Rainy Days?
1 Answers
Here are the reasons why an underbone motorcycle frequently stalls on rainy days: Stalling caused by rainwater infiltrating the fuel system: The fuel system, commonly referred to as the fuel supply system, mainly includes components such as the fuel tank, carburetor, and air filter. Rainwater primarily infiltrates through three pathways. It can enter through the fuel tank cap (Guy), flow into the fuel tank, and then into the carburetor. It can also be sucked in through the air filter intake and eventually reach the carburetor. Additionally, rainwater can directly enter the carburetor through its own vent pipe. Stalling caused by rainwater entering the electrical system: The electrical system here mainly refers to the ignition circuit, which includes the charging and pulse coils, electronic igniter, ignition coil, spark plug cap, spark plug, and a kill switch. The components most susceptible to rainwater intrusion are the spark plug cap and the kill switch. Occasionally, some igniters and ignition coils with poor moisture resistance may also be affected.
