front part with a 4# inner hexagon. For instructions on
disassembly and assembly of swell nails, please refer to the
pre-service instructions in this chapter.
j. Press the blue part inward at the junction of green and
blue as shown in the figure; pull the red and green
components outward. Then apply force from the rear wheel
to the front wheel along the junction of the red and blue
parts, push the red part outwards, and force the blue parts
inward to break apart. Remove the right pedal and right
pedal trim cover assembly.
k. Use a dust blow gun to blow away the dust and debris
near the spark plug.
l. Pull out the ignition coil high-voltage cap.
m. Remove the spark plug by turning it counterclockwise
with the vehicle-mounted tool or special 16# spark plug
sleeve.
n. It is recommended to seal the spark plug installation
hole with masking paper or other soft plastic bags to prevent
foreign matter from entering the engine.
2. Check the spark plug
a. Check whether the insulator is cracked or damaged,
whether the center electrode is abraded, fouled, corroded,
excessively carbonized or discolored (the color of the ceramic
insulator around the middle electrode of the spark plug
should be light brown). If so, replace the spark plug with a
new one.
b. Clean the electrode with a special spark plug cleaner.
Use a hard iron wire or steel needle to remove the attached
carbon deposits.
c. Use a feeler gauge to inspect the gap between the
center electrode and the side electrode.
d. If necessary, the gap can be adjusted by bending the
side electrodes, paying attention to the strength during
adjustment.
e. Clean the surface of the spark plug gasket and the joint
surface, and wipe off the dirt on the thread.
f. First screw it back to the engine by hand, and then use
the tool to turn it clockwise to the standard torque.
Model: NGK CR8EI-8
Resistance between the terminal screw and the center
electrode: 3
～
7.5kΩ
Clearance: 0.7-0.9mm (0.028-0.035in)
Torque: 14N.m (1.4kgf.m, 10 lbf.ft)
3. Refer to the steps to remove the spark plug to
restore all parts.
●The vehicle must be parked on a flat and stable ground or a
lifting platform.
●The operation can only be performed after the engine has
cooled down completely.
●Do not pull or knock the center electrode.
●If the replacement of inappropriate heating value or inferior
spark plugs causes engine damage, it is not within the scope
of the three guarantees.
●When installing the spark plug, the torque should not be
too large, and the thread should be screwed in manually
before tightening. If there is no torque wrench to replace the
spark plug, you can turn it by hand until there is resistance
and then rotate it 1/2 turn. For example, if you use an old
spark plug, you can turn it to the standard torque as soon as
possible.
●Pay attention and order when removing the plastic buckle
to avoid the buckle from breaking.
