SAFETY INFORMATION

is veering wide on a turn due to
EXCESSIVE SPEED or undercor­nering (insufficient lean angle for
the speed). Never travel faster
than warranted by conditions.

●

Ride cautiously in unfamiliar ar­eas. You may encounter hidden
obstacles that could cause an ac­cident.

●

The posture of the operator is im­portant for proper control. The op­erator should keep both hands on
the handlebar and both feet on the
operator footrests during operation
to maintain control of the machine.

●

Never ride under the influence of
alcohol or other drugs.

Protective apparel

The majority of fatalities from machine
accidents are the result of head inju­ries. The use of a safety helmet is the
single most critical factor in the preven­tion or reduction of head injuries.

●

Always wear an approved helmet.

●

Wear a face shield or goggles.
Wind in your unprotected eyes

●

Shifting weights can create a sud-

den imbalance. Make sure that ac-

cessories and cargo are securely

attached to the machine before

riding. Check accessory mounts

and cargo restraints frequently.

●

Never attach any large or heavy

items to the handlebar, front fork,

or front fender. These items, in-

cluding such cargo as sleeping

bags, duffel bags, or tents, can

create unstable handling or a slow

steering response.

Accessories
Genuine Yamaha accessories have
been specifically designed for use on
this machine. Since Yamaha cannot
test all other accessories that may be
available, you must personally be re­sponsible for the proper selection, in­stallation and use of non-Yamaha
accessories. Use extreme caution
when selecting and installing any ac­cessories.
Keep these guidelines in mind for
mounting accessories in addition to

the vicinity of an open flame.

●

Never start the engine or let it run
for any length of time in a closed
area. The exhaust fumes are poi­sonous and may cause loss of
consciousness and death within a
short time. Always operate your
machine in an area that has ade­quate ventilation.

●

Always turn the engine off before
leaving the machine unattended
and remove the key from the main
switch. When parking the ma­chine, note the following:

●

The engine and exhaust pipe(s)/
muffler(s) may be hot, therefore,
park the machine in a place
where pedestrians or children
are not likely to touch these hot
areas.

●

Do not park the machine on a
slope or soft ground, otherwise it
may fall over.

●

Do not park the machine near a
flammable source (e.g., a kero­sene heater, or near an open

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 de­signed to use regular unleaded gaso­line with a pump octane number
[(R+M)/2] of 86 or higher, or a research
octane number of 91 or higher. If
knocking (or pinging) occurs, use a
gasoline of a different brand or premi­um unleaded fuel. Use of unleaded fuel
will extend spark plug life and reduce

Adjusting the front fork

The front fork is equipped with air
valves for adjusting the spring rate and
screws for adjusting the damping force.

WARNING

EWA10190

There should be no difference in air
pressure between the fork legs.

Spring rate

The total spring rate is adjusted by
changing the air pressure as follows.

1. Lift the front wheel off the ground

according to the procedure on
page 6-31.

NOTE:

When checking and adjusting the air
pressure, there should be no weight on
the front end of the vehicle.

2. Remove the air valve cap from

each fork leg.
