been back to its original position be-
fore riding; otherwise, serious acci-
dent may occur when turning.
3.After warming the engine, hold the
fixed bracket by right hand and push
the motorcycle off the center-stand.
4.Sit astride the seat and adjust the

WARNING

Since the exhaust pipe of muffle

OPERATION AND IMPORTANT RIDING POINTS■ ■■ ■
■Engine exhaustWe take the environmental protection
into consideration maturely, our mo-
torcycles are equipped with AIS sys-
tem and agent catalyzing device in the
exhaust pipe, and can meet the re-
quirement of Europe II emission
standard.
Massive incomplete combusted gas
mixture will re-combust when flowing
into the hot agent catalyzing device,
thus causes exhaust pipe overheat-
ing and shortens the service life of
catalyzing device. To prevent this kind
of situation and other damages,
please read the following list carefully.
CAUTION:

. Only use unleaded fuels (#93 un-
leaded petrol). The leaded petrol will
cause the catalyzing device be-
come contaminated and rendered
useless.. When riding, do not turn off the
main switch. Otherwise, it will pro-
duce massive incomplete com-
busted gases.. If the ignition or fuel system is
out of condition, the agent cata-
lyzing device will overheat.. Be careful when the motorcycle
rides for a period of time, the out-
side of exhaust pipe will be very hot.. Do not splash or overfill the fuel
to the exhaust pipe when re-fueling.
It may burn when the petrol drippedto hot exhaust pipe.
