Gear oil replacement
Gear oil needs to be replaced every 3,000Km or half a year,
whichever comes first. Always use SAE80W90 gear oil.

by using the main stand with
a pre-heated engine.
(2) Remove the gear oil drain
screw " B"to drain the used gear oil
into a container. Clean the gear oil
drain screw and reinstall the screw " B" .
(3) Remove the gear oil filling screw " A"to fill with about 110ml
gear oil, and then reinstall the screw " A"
Warning: Always check the gear oil level before and after driving
long distance. Always use the specified gear oil and don' t mix
with other gear oils. Make sure that gear oil drain screw is
tightened after being reinstalled. Be carefully when draining the
gear oil from a pre-heated engine, which may be very hot.
Carburetor
Good carburetor ensures the engine to work well. It is adjusted as the
best before engine delivered from the factory, so don't adjust it
casually. The carburetor is to be adjusted in two places, i.g. the
throttle cable adjustment and the idle speed adjustment. After the
initial 1,000km and every 6,000 km after that, they could be
adjusted.
Throttle cable adjustment
1. Loosen the lock screw " 1" .
2. Turn the adjusting nut " 2"to make
the free play of the cable between
0.5 and 1.00mm.
3.Tighten the lock screw after
adjustment, and covered by the rubber
cover " 3"for throttle adjusting nut
and lock screw.
Idle speed adjustment
1. Start the engine and keep it running
until it is fully warmed up.
2. With the engine warmed up, set free
the throttle grip and adjust the idle
speed screw " D"to set the idle speed
between 1,400rpm and 1,600rpm.
Caution: Adjust the idle speed of the engine when it is fully
warmed up.
Warning: After the throttle cable is adjusted, check the movement
of the throttle control grip. No increase in the idle speed of the
engine should be resulted in because of the adjustment and the
throttle control grip should be able to return to the close position
automatically.
