What are the reasons for a motorcycle not starting after being washed with water?

[VanBryce]

The reasons for a motorcycle not starting after being washed with water may include the following: 1. Damp spark plug cap: High-voltage leakage prevents ignition, which can be resolved by wiping the spark plug surface dry with a towel. 2. 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, then turn on the fuel switch to flush and tighten the lower shell screw. Pump the throttle a few times to start the engine. Precautions: 1. Note 1: Car washes may appear to have complete tools and standardized operations, but they often prioritize efficiency over effectiveness and may cause faults in spark plugs and various circuits. 2. Note 2: Always allow a hot engine to cool down before washing. Sudden cold water rinsing of engine parts, exhaust pipes, etc., can cause thermal contraction and damage oil seals, leading to engine oil leakage.
