What to Do When a Motorcycle Won't Start After Going Through Water?
2 Answers
When a motorcycle fails to start after water exposure, inspect the following components: 1. Check the spark plug: If the spark is weak or absent, focus on inspecting the electrical circuit. If the spark is strong, it indicates the circuit is functioning properly, and you should then remove the exhaust pipe to drain the water, and take off the air filter. If the filter element is wet, it needs to be replaced with a new one. 2. Check the air filter: Inspect whether the air filter is waterlogged or clogged. You can try starting the engine after removing the air filter. 3. Check the engine: If water has entered the engine cylinder combustion chamber, remove the spark plug and blow air inside to dry out the moisture.
I've encountered that issue a few times too. After riding through a puddle, the motorcycle won't start, usually because water got into critical components affecting ignition. First, don't panic and avoid repeatedly trying to start it, as this can worsen engine damage. Immediately push the bike to a dry area and turn off the power. Next, check these key areas: The air filter easily sucks in water—remove it to see if it's soaked. If wet, let it dry or replace it outright. Spark plugs often accumulate water too—carefully pull them out, wipe them dry, or use a hot air blower to dry them before reinstalling and testing. If it still doesn't work, water may have caused a short circuit at the battery connections—clean the electrode heads to ensure good contact. Wait ten minutes before trying to start it again. If it still won't fire, it's best to take it to a repair shop, as they can check deeper issues like faulty ignition coils. Avoiding deep water rides is crucial—go slow when crossing puddles to minimize risks.
