How can a motorcycle suddenly fail?

My motorcycle 10 days useless, and yesterday when I use the electronic ignition on the next. But ran 20 km after a pedestrian on the road to the oil after the less, it turned off. And then in the use of electronic ignition did not respond (foot start can). And when the speaker is sometimes not ringing (feeling like electricity shortage), the car when the speaker horn. Today check the battery electrolyte just under the line, add a little after 4 hours after charging the installation of no response, and then fire several times, and occasionally the relay squeak, the speaker is loud. Do not know what reason, ask you heroes help out? The

Answer:

check whether the spark plugs, coke, the spark plugs flash test. If the spark plug between the sparkless sparkling or spark short and short, then the spark plug work poorly, should check whether it is coke, spark plug insulation performance is in line with the requirements of the spark plug is damp, etc., and according to the specific circumstances to be cleared.
if the above normal, but before stopping, the engine speed into instability, the motorcycle in the driving red, off the small throttle speed becomes low, and the flame, should consider the battery power shortage, because the engine speed is high, by the Engine power supply ignition, the engine can maintain the operation; when the driving speed changes, the generator output current also changes. So that the ignition occurs intermittent, motorcycle hair red, when the small throttle, the speed is reduced, the generator is not generating or current is very small, the spark plug can not fire and turn off. At this time should be 22 to take emergency treatment, to be back after the charge.
check the battery wiring and low voltage wire of the various joints, high city wire and ignition coil terminal bundle loose, if any, should be timely maintenance.
Check whether the fuel is exhausted, according to whether the engine speed before the car suddenly automatically increase the phenomenon to determine, if any, then the fuel is exhausted, should be dumping the car to ask the vehicle for help, refueling can be used when the hose or plastic pipe siphon principle refueling , But at this time the lack of oil motorcycle should be lower than the fuel tank for the car can also be used on the motorcycle fuel tank cover, magnetic motor shield, plastic bags as a container for fuel, but in the fuel, the fuel switch Placed in the "closed" position, so as not to gasoline from the carburetor into the cylinder.
