CAUTION:
ECA11400
Use only unleaded gasoline. The use
of leaded gasoline will cause severe
damage to internal engine parts,
such as the valves and piston rings,as well as to the exhaust system.
Your Yamaha engine has been de-
signed to use regular unleaded gaso-
line with a research octane number of
91 or higher. If knocking (or pinging) oc-
curs, use a gasoline of a different brandor premium unleaded fuel. Use of un-
leaded fuel will extend spark plug life
and reduce maintenance costs.

it if damaged.
Make sure that the end of the fuel
tank breather hose is not blocked,
and clean it if necessary.

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.

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”

make starting easier. After the engine
has started, be sure to turn the lever to
“ON” (or “RES” if you have not refueled
yet).

Do not tamper with or attempt to
open the gas cylinders.
Do not subject the shock ab-
sorbers to an open flame or oth-
er high heat sources, otherwise
they may explode due to exces-
sive gas pressure.
Do not deform or damage the
gas cylinders in any way, as this
will result in poor damping per-
formance.
Always have a Yamaha dealerservice the shock absorbers.

Sidestand The sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.NOTE:The built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See further down for an explanation ofthe ignition circuit cut-off system.)
WARNING
EWA10240
The vehicle must not be ridden with
the sidestand down, or if the side-
stand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly as described
