Ask why the motorcycle can't start on a wet morning.

Motorcycle can't start in wet morning, which may be due to the high humidity of air inhaled by air filter and carburetor, which affects the quality of mixed gas, or the electrical components and wiring plugs of ignition system are wet, which affects the quality of high voltage electricity. You can try to start the damper. If it can't be started, remove the spark plug and check whether the spark plug is wet due to long-term starting. You can dry or replace the spark plug, continuously discharge the excess fuel mixture in the cylinder (start it by electricity or several times with your feet when the spark plug is not installed), and then install the spark plug to start it.
