\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
bran\b. Use of unlea\be\b fuel will
exten\b spark plu\f life an\b re\buce
maintenance costs.

Fuel tank breather/over\flow
hose
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.
