Gasoline is poisonous and can
cause injury or death. Handle gaso-
line with care. Never siphon gaso-
line by mouth. If you should swal-
low some gasoline or inhale a lot of
gasoline vapor, or get some gaso-
line in your eyes, see your doctor
immediately. If gasoline spills on

\bse only unleaded gasoline. The use
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)
occurs, use a \fasoline of a \bifferent

exten\b spark plu\f life an\b re\buce
maintenance costs.

Before operatin\f the motorcycle:
Check the fuel tank breather/over-

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

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.

lowing information before handling
the shock absorber \4assembly.
●Do not tamper with or attempt
to open the cylind\4er assembly.
●Do not subject the shock ab-
