How to Deal with a Motorcycle That Won't Start After Water Enters the Fuel Tank?
2 Answers
If water enters the fuel tank, do not attempt to start the engine and send it for repair immediately. Water in the fuel tank can also enter the oil compartment, and forcing the engine to start may cause severe damage or even engine failure. Common motorcycle faults: 1. Blue smoke from the exhaust pipe: The symptom of blue smoke is that during engine operation, light blue smoke is often visible at the tail of the exhaust muffler, accompanied by excessive oil consumption. Possible causes include: oil level too high; cylinder compression pressure below the specified value; increased clearance between the piston, piston rings, and cylinder wall. 2. Black smoke from the exhaust pipe: The symptom of black smoke is that the exhaust emits black smoke during engine operation, with a noticeable pungent gasoline smell, especially during acceleration. Possible causes include: overly rich air-fuel mixture; faulty spark plug; delayed ignition timing.
Once my motorcycle wouldn't start after riding in the rain, and I later found water had entered the fuel tank. It was really frustrating at the time! Now I'd like to share some handling experience. First, don't force start the engine as this can damage it. Immediately push the bike to a safe location. Next, drain the fuel tank: open the fuel cap and use a siphon or hose to remove the water-fuel mixture. Cleaning the tank is crucial - either wipe the interior dry with towels or have it professionally cleaned at a repair shop. Also check the spark plugs; replace them if wet. Finally, add fresh fuel and try starting. If it still doesn't work, there might be issues with the fuel pump or filter. For prevention, I now always check the fuel tank's seal after parking in rain or use a waterproof cover. Never underestimate water ingress - it can corrode components! My advice is to consult a professional mechanic if you can't handle it yourself, to avoid bigger troubles.
