The fear of stalling during rainy weather is a common concern for those who use motorcycles for off-road adventures. If not handled properly, the bike can break down. In this article, RuudNguyen.com will guide you on how to deal with motorcycle stalling issues during rainy seasons, especially in flooded areas.

Based on my years of experience, there are three main reasons for a motorcycle stalling when entering a flooded area.
- First, water entering the spark plug prevents it from igniting.
- Second, water can enter the exhaust pipe, causing blockages and potentially reaching the engine, leading to stalling.
- Third, water entering the air intake pipe can flow down and mix with the fuel, preventing the motorcycle from starting.
What to Do When Your Motorcycle Gets Flooded

Unfortunately, while riding, if your motorcycle suddenly shuts down, the first thing you need to do is get off the bike and push it out of the flooded area. You should not attempt to restart the motorcycle as doing so may damage the engine. When you encounter a flooded road, observe and estimate the depth before deciding to proceed.
Experienced riders suggest that with motorcycles, you should avoid riding into sections where the water level approaches the exhaust pipe or submerges half of the wheel. If you proceed, water can easily enter the exhaust pipe, causing blockage and the motorcycle to stall.
For manual transmission motorcycles

Always ride in a lower gear when passing through deep water on manual transmission motorcycles like Honda, Yamaha, Exciter, etc. If your motorcycle gets submerged in water, it’s essential to take immediate action. The best approach is to push your motorcycle to a drier area.
Please note that if you attempt to start the engine 1-2 times without success, do not attempt to start it again. Doing so will only worsen the condition of the motorcycle.
If you successfully restart the engine and get through the flooded area, it’s important to change the engine oil. If the motorcycle stalls due to water, immediate repairs are necessary because dirty water may have entered the exhaust system or the pressure balance hole. If your motorcycle stalls due to flooding during rainy weather, you need to drain all the oil from the engine compartment. After draining the oil, you should replace it with fresh oil.
Furthermore, you should also ensure that the braking system is dried. This step will protect the braking system from squeaking and corrosion. To ensure the long-term stability of your motorcycle, it’s advisable to regularly bring it to a nearby dealership for maintenance.
For scooters
Due to their special design, some scooters often have low gearbox ventilation pipes, making them susceptible to rainwater penetration.
Scooters, when passing through flooded areas, tend to suck water into the engine, similar to cars. If the rider intentionally tries to start the engine after the scooter stalls due to water immersion, it will lead to the mixing of water with oil, affecting various engine components. Therefore, the engine is at risk of corrosion after only a few kilometers of riding.
If your scooter is submerged in water, quickly push it out of the waterlogged area, look for nearby repair shops, or you can attempt basic remedies as follows:
- Remove the spark plug, dry it thoroughly, and reinstall it. Remember the spark plug location for each scooter type and have the necessary tools for removal and installation ready when traveling.
- Drain all the oil from the engine compartment and replace it with new oil.
- Dry the brake system.
- Use grease or engine oil to clean the chain, kickstand, and starter lever.
Several notes when moving into a flooded road

When riding on a flooded road, remember to maintain a steady throttle, as sudden acceleration and braking can cause your motorcycle to stall more easily. In areas with limited visibility, it’s best not to attempt overtaking. On flooded roads, keep your motorcycle in gears 1 or 2 and maintain a steady throttle until you pass through.
Also, be sure to maintain a safe speed in flooded areas, as it can affect your road safety. Floodwater can obscure speed bumps on the road, so be cautious.
Furthermore, avoid driving parallel to cars, especially buses, in flooded areas. The force of the waves created by these vehicles can be a cause of falling or getting splashed with water.
You should also avoid taking shelter under trees during rain or riding on roads with many trees to avoid the risk of falling trees, debris, or lightning strikes while riding. When you encounter strong winds, either find a shelter or ride on open, less wooded roads.
