Ignition system inspection
Caution:
●If there is no spark in the spark plug, check all the cable connections for looseness or poor contact before checking the ignition
system.
●Use a high -precision digital multimeter.
For details of the ignition coil test method, please refer to the section "Ignition Coil" in the "Electronic Injection System"
chapter of this manual.
Pull out the high-pressure cap, find a spark plug of the same model that is confirmed to be normal, and install it on the high-
pressure cap close to the cylinder head cover to do an ignition test to confirm whether the ignition coil is faulty.
Refer to the crankshaft position sensor section in the "Electronic Injection System" chapter of the "Electronic Injection
System" chapter of this manual to check whether it is abnormal.
Ignition timing
Caution:
●The ignition timing is preset in the ECU before leaving the
factory and cannot be adjusted. If adjustment is required,
the engine can only be returned to the factory for repair.
●If the right crankcase cover and cylinder head cover of the
engine are removed to check the timing, the crankcase
cover gasket must be replaced; it is recommended that the
cylinder head cover gasket is also replaced and the sealant
should be applied to the position shown in the figure.
●Because professional tools and equipment are required to
assemble, detailed step-by-step instructions are not given
here, only a rough explanation.
Refer to this manual for the method of disassembling the
rear damping assembly of the engine's rear wheel and
remove it first; then remove the peripheral parts of the
engine. Pack the whole engine and return it to the factory
for maintenance through logistics or express delivery.
