o\f 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 en\fine has been \besi\f-
ne\b to use premium unlea\be\b \fasoli-
ne with a research octane number of
95 or hi\fher. If knockin\f (or pin\fin\f)

1. Fuel tank breather/hose
2. Hose clamp
Before operatin\f the motorcycle:
Check the fuel tank breather/over-
flow hose connection.
Check the fuel tank
breather/overflow hose for
cracks or \bama\fe, an\b replace it
if \bama\fe\b.
Make sure that the en\b of the fuel
tank breather/overflow hose is
not blocke\b, an\b clean it if
necessary.
Make sure that the en\b of the fuel
tank breather/overflow hose is
positione\b insi\be of the clamp.
EAU13433
Catalytic converters
This vehicle is equippe\b with catalytic
converters in the exhaust system.
EWA10862
The exhaust system is hot a\fter
operation. To prevent a \fire hazard
or burns:
Do not park the vehicle near
possible \fire hazards such as
grass or other materials that
easily burn.
Park the vehicle in a place
where pedestrians or children
are not likely to touch the hot
exhaust system.
Make sure that the exhaust
system has cooled down be\fo-
re doing any maintenance
work.
Do not allow the engine to idle
more than a \few minutes. Long
idling can cause a build-up o\f
heat.

OPERATION AN\f IMPORTANT RI\fING POINTS
EAU15951
Read the Owner's \fanual care\bully to
become \bamiliar with all controls. I\b
there is a control or \bunction you do not
understand, ask your Yamaha dealer.
EWA10271
\bARNING0
Failure to familiarize yourself with
the controls can lead to loss of con-
trol, which could cause an accident
or injury.

TIP
This model is equipped with a lean an-
gle sensor to stop the engine in case
o\b a turnover. In this case, the multi-
\bunction display indicates error code
30, but this is not a mal\bunction. Turn
the key to "OFF" and then to "ON" to
clear the error code. Failing to do so
will prevent the engine \brom starting
even though the engine will crank
when pushing the st\sart switch.
EAUB1570
Starting the engine
In order \bor the ignition circuit cut-o\b\b
system to enable starting, one o\b the
\bollowing conditions must be met:
●The transmission is in the neutral
position.
●The transmission is in gear with
the clutch lever pulled and the
sidestand up.
EWA10290
\bARNING0
●Before starting the engine,
check the function of the igni-
tion circuit cut-off system ac-
cording to the procedure de-
scribed on page 4-18\ .
●Never ride with the sidestand
down.
1. Turn the key to “ON” and make sure that the engine stop switch is
set to “
I”.
