OPERATION AND IMPORTANT RIDING POINTS
■ ■ ■ ■ ■
Engine exhaust
We 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 dripped
to hot exhaust pipe.
