If your bike engine stopped taking load after riding in flooded rainwater, it's possible that water may have entered the engine or affected some crucial components. Here are a few potential reasons and solutions for your situation:
Water in the air intake: Riding through flooded rainwater can lead to water entering the air intake system. This can cause the engine to struggle and lose power. To resolve this, you can try removing the air filter and drying it thoroughly. Additionally, drain any water that may have accumulated in the airbox. Once everything is dry, reinstall the filter and try starting the bike again.
Wet electrical components: Water can affect the electrical system of your bike, causing issues with spark plugs, ignition coils, or other electrical connections. Check for any signs of water damage or moisture in the electrical components. If you find any, carefully dry them using compressed air or a hairdryer set to a cool setting. Ensure all connections are secure before attempting to start the engine.
Water in fuel system: If water entered the fuel tank or contaminated the fuel, it can lead to poor combustion and engine performance issues. In such cases, drain the fuel tank completely and clean it if necessary. Refill the tank with fresh fuel from a reliable source and consider using a fuel additive designed to remove any residual moisture from the system.
Engine hydrolock: Hydrolock occurs when water enters the combustion chamber, preventing the engine from turning over. If you suspect hydrolock, do not attempt to start the engine, as it may cause severe damage. Instead, it's best to have a professional mechanic inspect the bike and take appropriate measures to remove the water from the engine.
In any case, if you're unsure about performing these tasks yourself or if the problem persists, it is highly recommended to consult a qualified mechanic who specializes in motorcycle repair. They will have the expertise and tools necessary to diagnose and resolve the issue effectively.
