17.4.3.8
Fault Description- Little Misfire
Check whether the spark plug gap meets the standard between 0.7-1mm.
17.4.3.9
Fault Description- Non-conformity between Fault Code and
Fault
When Trouble Light is On
The ground wire of the system may be not connected well. Reconnect the ground wire,
turn off the storage battery power line for 3 minutes and turn it on, then start the engine.
17.4.3.10
Fault Description- Abnormally High Oil Consumption
a) Check the assembly of the oxygen sensor of two cylinders. If it is in a loose state, the oxygen
sensor will make a wrong judgment of the slight lean burn in the cylinders, and thus add
more fuel, leading to abnormally high oil consumption.
b) When the engine's mechanical parts and the oxygen sensor are confirmed to be normal, start
the engine to check the reading of the oxygen sensor. If the reading is always above 500
mV in a normal water temperature, check whether there is a leakage in the oil nozzle.
Note
Most parts of electronic control injection system are non-repairable. Once a part is damaged,
usually it needs to be replaced.
When starting the engine, do not run any other organs of the engine (including the throttle, do
not push the throttle in the startup).
If the engine trouble light turns on when the engine is operating, it is necessary to check the
reason and remove the fault as early as possible.
Do not use leaded gasoline for lead will do harm to the oxygen sensor and ternary catalytic
converter.
When there is an abnormal consumption of the engine oil, the fault should be removed as soon
as possible, or some substances in the engine oil will also do harm to the oxygen sensor and
ternary catalytic
converter.
The air valve clearance should not be too small. If the air valve does not tightly shut off in the
exhaust process, the exhaust temperature will be too high so that the service life of ternary
catalytic converter will be reduced.
When the temperature is lower than 10℃, if the motorcycle and the engine run at a low speed
for a long time, the exhaust pipe may have carbon deposits and appear to be black. This is a
normal phenomenon. It will disappear after the engine operates at a high speed for some time
or by adopting appropriate methods to keep the engine coolant temperature in a specified
range
