Gasoline is dripping from your carburettor. This failure is dangerous! Follow these simple gestures to overcome these small inconveniences. Very often the leaks come from the tank, float and float needle .
1) In the carburetor bowl, float regulates the fuel level. In the carburettor, when an impurity gets stuck on the float needle leakage is assured. Try tapping on the carburettor, the generated shock wave allows to take off the impurity.
2) If there is no result, close the fuel tap and empty it carburetor bowl by unscrewing the bleed screw provided for this purpose. Once the tank is empty, open the valve (if your bike has one) and kick the starter. Free-flowing gasoline cleans up dirt. If you have compressed air, disconnect the hose from the valve and give it a little blow of the blower. This drives out the impurities.
3) If the leak persists, disassemble the carburettor to check the level of the float. A tank level must be respected.
4) When the float needle is open, it allows gasoline to pass into the fuel tank. tank. When this tank is full, the float back up to block the float needle to its closed position. If gasoline leaks from the carburettor par the overflow, inspect the float needle : If it is stuck or there is dirt, it will prevent sealing. If it is marked, then it must be replaced.
5) If the problem persists, check the wear of the gasket toroidal seat (well) of float needle . If it is damaged, change it.
