●Remove the throttle valve body to clean the carbon
deposits and operate in a dust-free and dust-free
environment to prevent dust from entering the inside of the
engine.
●Prevent foreign matte r from falling into the engine or air
filter.
●If the stepper motor, sensor and heat insulation pad are
disassembled, do not miss the sealing ring and make sure
that the sealing ring is assembled in place without cutting
edges.
●Do not use carburetor clean er or compressed air to clean
the throttle valve body.
●The EFI system needs to be reset after reinstalling the
battery.The specific method is as follows:
a. Unlock the vehicle and support the main bracket;
b. Pinch the brake and start the vehicle;
c. Pull the engine speed above 3000 rpm;
d. After releasing the throttle, turn off the flameout switch
and lock the car;
e. After waiting for 5 seconds, unlock the vehicle again to
complete the reset of the EFI system.
Throttle cable
1. Inspection
a. Check whether the rubber sleeve of the right hand
handle and the throttle cable are damaged.
b. Check whether the rubber sleeve of the right hand
rotates smoothly and whether it can return automatically.
c. Hold the steering wheel with both hands and turn the
right hand to the right while rotating the rubber sleeve of the
right handle. Every time you turn a certain steering angle,
confirm whether the throttle can be reset normally. If you
can’t reset it, you need to lubricate the cable or the inside of
the right handle; or replace it with a new throttle cable or the
rubber sleeve of the right handle.
d. After starting the engine, turn the steering handle left
and right to ensure that the idling speed does not change
during the steering process, and then turn off the engine.
e. Rotate the right hand to check whether the rubber
sleeve inspection cable gap is within 2
～
4mm (0.1
～
0.2 in).
2. Adjust the throttle cable clearance
a. Fix the adjusting screw ② with a 8# open-end wrench,
and then use a 10# open-end wrench to loosen the nut ①
counterclockwise. Rotate the adjustment solenoid ②
clockwise to reduce the free stroke, counterclockwise to
expand; adjust the gap to the specified value. After adjusting
the gap, tighten the nut ① .
Torque: 3.8 N.m (0.4 kgf.m, 2.8 lbf.ft).
b. If the above adjustment fails to achieve the desired
effect, please refer to the description in "Remove the throttle
valve body assembly to clean up carbon deposits" to remove
the throttle valve body assembly. Use a 10# open-end
wrench to loosen the 2 nuts on the bracket to adjust. Torque:
3.0 N.m (0.3 kgf.m, 2.2 lbf.ft).
c. If the above two adjustments are invalid, replace the
throttle cable with a new one.
3. Lube door cable
If the rotation resistance is large and the bending of the
throttle cable and the loose strands of the wire core can be
eliminated, add a proper amount of lubricating oil, such as
sewing machine oil.
a. Remove 2 bolts ⑴ with a 5# inner hexagon, and move
the upper part of the switch away.
b. Use a syringe to draw a small amount of sewing machine
oil several times and inject it from the gap between the
throttle cap and the thread core, and turn the throttle while
injecting.
c. If the problem with high resistance cannot be solved
after lubrication, the throttle cable needs to be replaced.
