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.
d. Check whether the weld at the bottom of the shock
absorber is leaking.
2. Adjust the preload
The rear shock absorption of this vehicle can be adjusted
according to the needs of the owner. Sort 1-5 levels, level 1 is
the softest, level 5 is the hardest, and the factory defaults to
level 2. Turning the compression spring preload length to the
H direction makes the shock absorption harder; otherwise,
the shock absorber becomes softer. The two rear shock
absorbers need to be adjusted to the same gear.
2.1 Adjust the right rear shock absorption
Use the 5# inner hexagon to insert into the hole of the
right rear shock absorber adjuster, and rotate to the required
gear in the direction of the arrow.
