d. Check whether there is any leakage at the bottom of the
bottom cylinder with the help of a mirror or mobile phone
lens. If there is a slight leakage, first check whether the bolts
are loose. The bolt torque here is 20
～
26N.m (2
～
2.7 kgf.m,
15
～
19 lbf). ft). If there is still leakage after tightening, the
gasket should be replaced.
2. Check the shock absorption performance
Pinch the front brake handle and press down forcefully.
After releasing it, it should be able to compress smoothly and
then return to normal. Repeat the operation several times to
check. If there is a block, the shock absorber needs to be
removed for investigation. If there is a collision with the front
wheel or a high-speed bump, check whether the shock
absorber is deformed. Check the shock absorption
performance according to the maintenance schedule. It is
necessary to prevent the vehicle from turning over during
operation.
3. Remove the front shock absorption
Remove the front shock absorber according to the steps of
removing the front shock absorber in the "Front Fork
Assembly" of this manual.
4. Correct the front fork tube
If the front wheel of the vehicle passes a hurdle at a high
speed or after a collision, check whether the front fork tube
is deformed. Take the left shock absorption as an example.
Use the end face of the front axle of the shock absorber
bottom tube and the end face of the front fender mounting
point to fix the shock absorber; or remove the front fork
tube. Use a dial indicator to detect the amount of
deformation in the axial direction of the front fork tube, and
rotate the front fork tube to measure different positions.
For slight deformation of less than 0.2mm (0.008 in), the
front fork tube can be supported by a V-shaped iron block,
and soft rubber, rubber, copper, etc. should be placed on the
contact surface to prevent the front fork tube from being
scratched. Use the press slowly and slightly, straighten the
pressure and small stroke several times, and measure while
straightening. The radial run out after correction should be
less than 0.05mm (0.002 in). If the original bending
deformation part is out of round after correction, it should be
replaced. If the deformation is too large, the shock
absorption should be replaced.
5. Troubleshooting
a. There is obvious impact noise when driving on uneven
roads or emergency braking. The following items need to be
checked:
Whether the spring of the shock absorber is broken or the
elasticity drops;
Whether the hydraulic oil is insufficient or enters the air;
Whether there is too much hydraulic oil;
Whether the spring is axially bent and rubs against the
front fork tube.
b. The following items should be checked for excellent
shock absorption:
Whether there is too much hydraulic oil;
Whether the front fork tube is bent or deformed;
Has the spring been modified?
c. If the shock absorption is too soft, check the following
items:
Whether the hydraulic oil with low viscosity is changed;
Whether the spring force drops;
Is there too little hydraulic oil?
Rear shock absorption
Caution:
●If the rear shock absorber has a lot of mud and sand, it
should be cleaned in time to prevent soft and big stones from
scratching the chromed parts and causing rust.
●Non -professionals should not disassemble the rear shock
absorber by themselves.
●It should be maintained according to the regular
maintenance table.
1. Check
a. One person straightens the vehicle and stabilizes the
vehicle, and one person presses the rear armrest behind to
observe whether the rear shock absorber can recover
smoothly.
b. Check whether the shock-absorbing bolts are loose.
c. Grasp the upper part of the damping spring and rotate it
in the radial direction. It should be able to rotate in a small
amount. Check the bottom in the same way. If the upper part
cannot be rotated, the shock-absorbing rubber buffer sleeve
has aged and failed; if the bottom cannot be moved, the
buffer sleeve on the rear rocker arm and the engine box has
failed and needs to be replaced.
