Regulator

Measure resistances among connecting line
ends by multimeter(See below Picture). If one
value is out of specified range. Please replace a
new one.

  Turn Meltimeter on Diode

  Caution

:

   When Multimeter probe is unconnceted,
   Multimeter voltage is below than 1.4V,
   Please replace Multimeter Battery.

When Engine gets started and battery is fully
charged, if the voltage between  red line and
green line is more than 15V or less than 12V,
please replace it with  a new one.
(Engine at 5000rpm)

Caution when starting engine

7.Connect the lines according to circuit diagram.

8.Check whether parts are connected properly

    before starting.

9.Check air circulation system.

10.Check fuel system.

  If blocked, clean clogged parts and ensure smooth

fuel system.

  If leakage, try to reconnect the leaked parts and  en-

sure leakless fuel system.

Ignition system Diagram

Ignition coil primary voltage

1.Keep spark plug in the cylinder head, install quali-

fied spark plug on the spark plug cap and earth the

engine.
2. Measure the primary voltage of Ignition coil by

multimeter.

3.Connect multimeter and peak value voltage  adapter

as follow:
          + Probe: Green Downlead/Ground
          - Probe: Black/Yello Downlead

Notice

:

  Confirm the voltage of battery 12V
  Downlead of Ignition coil is connected.
 Refer to User Guide when using Multimeter
  and Peak value voltage adapter

Ignition coil

4. Turn the gear at Neutral, and Turn the ignition switch
at ¡°ON¡±.Run the engine few seconds by pushing
startig buttin, and measure Peak value of Pick-up Coil.

5. Repeat few times to get the highest peak value.
Turn Mulitimeter to AC.
  

Ignition coil primary Peak value  12V

Warnning

 When measuring the voltage, do not touch the termi-

nal with finger to avoid electric shock.

Overhaul information

Notice

1.Headlight bulb has larger power and the temperature is very high when it is turned on. Do not touch it

immediately after it is just turned off. Operation should be done when the bulb is cooled down.

2.The temperature of headlight is quite high when turned on. Replacing with bare hand or stained glove will

cause oil stains on the glass cover which may form heat points and cause deformation of glass face and

damage to bulb.

  3.Pay attention to the following points when replacing the bulb.

  £-Do not replace the bulb when it is turned on. Keep ignition switch in the “OFF”position, and replace after the

bulb is cooled down

.

  £-Replace the bulb with hands in clean gloves.

   4.Clean the glass with a piece of clean cloth dipped in alcohol in case of any oil stains on the surface.

  5.If the Inspection has to be done with battery, check if the battery is normal.

  6.Inspection of switches can be done without removing the switches from the vehicle.

  7.After the inspecting and overhauling of each part, routing of cables and wires should pass through the

proper positions.

Caution

Note

Gasoline is highly flammable, therefore smoke and fire are strictly forbidden in the work

place. Special attention should also be paid to sparks.  Gasoline may also be explosive

when it is vaporized, so operation should be done in a well-ventilated place.

1.

Do not over twist or bend the cables. The twisted cables may cause poor operation.

2.

To prevent impurities from entering into the engine after the carburetor is removed, cover the

engine air intake opening with a piece of cloth or packing tape.
