How to Fix a Xingfu 250 Motorcycle Carburetor Not Supplying Fuel?

If the motorcycle is not getting fuel, simply thoroughly clean the carburetor. The oil and water in the air filter assembly are produced by the engine. There is a transparent plastic tube in front of the air filter; remove the plug of the tube to drain the water. Because the engine's lower exhaust is slightly excessive, the generated exhaust gas passes through the waste gas pipe of the cylinder head and is recycled by the air filter.
I've encountered a similar situation before. When the carburetor isn't supplying fuel, it's mostly caused by a blocked fuel line or a dirty carburetor. Just like with my old bike that time, the fuel pump wasn't working because too much debris had accumulated in the fuel tank outlet filter. I suggest you first check if there's sufficient fuel, then inspect the fuel line connections for any looseness or blockages. If everything seems fine, remove the carburetor and clean its internal components, being careful not to apply excessive force during cleaning to avoid damaging the seals. If it still doesn't work after cleaning, check the fuel pump's operation status, and adjust the throttle setting if necessary. It's best to perform regular maintenance on the fuel system to prevent similar issues from recurring. After all, a stable bike condition ensures a worry-free and comfortable ride.
Carburetor fuel supply issues are quite common, usually caused by clogged fuel lines or carburetor malfunctions. I often help friends fix such problems. The first step is to check if the fuel tank has sufficient fuel, then inspect whether the fuel lines are bent or blocked. If the fuel pump is working but there's no fuel output, cleaning the carburetor filter and nozzles usually solves the issue. Another possibility could be a stuck fuel valve or poor sealing—gently twisting it to see if fuel flow resumes. If all else fails, check the ignition system coordination, as sometimes electronic control deviations can affect the fuel supply timing. Developing regular maintenance habits can significantly reduce the chances of such issues. For example, I check the fuel lines monthly, which saves a lot of trouble.
