What Causes a Motorcycle Not to Start After Being Washed with Water?

[LillianaRose]

The reasons why a motorcycle may not start after being washed with water could be the following: Moisture in the spark plug cap: High-voltage leakage prevents ignition, simply wipe the exterior of the spark plug with a dry towel. Water entering the carburetor through the throttle cable: It is necessary to turn off the fuel switch, loosen the carburetor lower shell screw to drain water and fuel, turn on the fuel switch to flush it clean and tighten the lower shell screw, then kick-start several times to start the engine. Here is some relevant information: Note 1: Although car washes may seem well-equipped and operate with standardized procedures, their pursuit of efficiency often leads to subpar results, and they may also cause faults in the spark plug and various wiring. Note 2: Always allow a hot engine to cool down before washing. Suddenly rinsing the engine, exhaust pipe, and other components with cold water can cause thermal expansion and contraction to damage the oil seals in various parts, leading to oil leakage in the engine.
