Catalytic converter This vehicle is equipped with a catalytic
converter in the muffler.
WARNING
EWA10860
The exhaust system is hot after op-
eration. Make sure that the exhaust
system has cooled down before do-ing any maintenance work.CAUTION:
ECA10700
The following precautions must be
observed to prevent a fire hazard or
other damages.
Use only unleaded gasoline.
The use of leaded gasoline will
cause unrepairable damage to
the catalytic converter.
Never park the vehicle near pos-
sible fire hazards such as grass
or other materials that easily
burn.
Do not allow the engine to idletoo long.
EAU13570
Fuel cock The fuel cock supplies fuel from the
tank to the carburetors while also filter-
ing it.
The fuel cock lever positions are ex-
plained as follows and shown in the il-
lustrations.
ON
With the fuel cock lever in this position,
fuel flows to the carburetors when the
engine is running. Turn the fuel cock le-
ver to this position when starting the en-
gine and riding.RES
This indicates reserve. With the fuel
cock lever in this position, the fuel re-
serve is made available. Quickly turn
the fuel cock lever to this position if you
run out of fuel while riding, otherwise
the engine may stall and will have to be
primed (see “PRI”). After turning the
fuel cock lever to “RES”, refuel as soon
as possible and be sure to turn the fuel
cock lever back to “ON”!1. Arrow mark positioned over “ON”
