A, why some motorcycle YinYuTian starting difficulties? Some motorcycle summer YinYuTian cold start difficult, even more so. After the engine running instability, easy to stall, there burning inadequate symptoms, driving after the start driving weakness, after a period of time the engine is running normally.
Encounter this kind of phenomenon, should tear open next spark plug, if do jump fire test that spark strong ignition system, the normal. Carefully check whether there is tiny cracks in the spark plug hat, then shall take spark plug hat relaxation in spark plug in, if the cold starting to car engine, but also can hear starting between strong spark plug hat that spark jump strike sound have tiny cracks in the spark plug hat in air damp summer, starting YinYuTian air breakdown, caused by machine stops fire caused the spark plugs. When the engine preheating, because the engine itself heat release, make the spark plug hat ambient air relatively dry, insulation resistance increases, the high voltage cannot breakdown crack in the air, so the engine and resume normal work. Second, motorcycles in the course of driving gradually decelerate automatic flameout what reason be? How to exclude?
Electric motorbike in motion, engine slowing gradually be automatic flameout, and slowly in flameout obviously felt powerless before, are generally engine fuel system fault, then should check whether the fuel tank with within, if fuel sufficient should check whether the switch, tear off fuel, then pulled out a fuel supply pipeline check whether, if without fuel oil supply, explain the carburetor jams, should dredge fuel oil. Simple method to remove the faults, first will switch to the closed position, and twisted removed and the oil tank switch, and then connected with the mouth to blow air (or pipeline pump cheer with). The impact of the compressed air within the blockage, carburetor oil-way possible, if oil dredge still impassability, shows that oil seere blockages, should tear open next carburetor thoroughly clean.
If the engine flameout process, issued a larger "sound, remove from heat as' not starting, foot starting lever feel compression force is small, can judge the cylinder head pad has been burning through, or the crankcase oil seal damage. Four training should also be considered process engine valve for burnt out and leak, valve follower. Detachable bending under factors such as the valve cover, air cushion check, if the cylinder head mat wear loss, should be replaced new pieces. If no damage cylinder cushion phenomenon, should check the crankcase oil seal is damaged, the crankcase oil seal can be unloaded parts, and remove oil seal outside inspect smoke. If oil seal, should replace new thing bad.
Three, separation lubrication oil pump flow should how to adjust
The size of the pump flow, should with the opening of the carburetor section valve matching. If oil supply is too big, combustion is not full, muffler, smoke wh3en starting difficulties, spark plug coke, if oil to supply is too small, engine overheating, wear increased, even can cause bilge cylinder. Therefore, make the oil pump flow and gasoline supply synchronization is a very important problem. General every driving around 6,000 kilometers, responding to a pump flow adjustment. Pump flow by manipulating cables, adjust the length of steel cable control, can change the size of the pump flow.
People prefer to use dirt bike , not only environmental protection and in support of the city speed could quickly.
