It is normal that the accelerator of parallel bars EFI motorcycle is small. If you give a big throttle, it will suddenly cut off oil. What happened? Suddenly it broke, just like a lever working online, waiting for an answer. The carburetor is broken.

If the flameout is regular during driving, it may be that the ignition system has a hot car flameout phenomenon. Check whether the stator coil (including trigger coil), igniter, high voltage package and electric door lock of magneto are normal.

Because the scooter is a negative pressure fuel tank switch, if the engine is turned off during driving, even if the parking time is longer, the fuel tank will not produce oil, and it must be operated by the engine to absorb oil. In addition, check whether the air filter and carburetor are blocked, whether the fuel tank switch is damaged, and whether the hose is aging and leaking oil.

If the engine flameout after heating, it may be caused by too small valve clearance (this phenomenon is rare, and most inexperienced maintenance masters don't believe it). Then close the damper and open it normally, then check the sealing condition of the joint between carburetor and engine (the rubber joint between carburetor and engine of 125 is prone to air leakage), and then check whether the air filter element is dirty.
