Be a Responsible Owner
As the vehicle’s owner, you are re-
sponsible for the safe and proper oper-
ation of your motorcycle.
Motorcycles are single-track vehicles.
Their safe use and operation are de-
pendent upon the use of proper riding
techniques as well as the expertise of
the operator. Every operator should
know the following requirements be-
fore riding this motorcycle.
He or she should:  Obtain thorough instructions from
a competent source on all aspects
of motorcycle operation.
 Observe the warnings and mainte-
nance requirements in this Own-
er’s Manual.
 Obtain qualified training in safe
and proper riding techniques.
 Obtain professional technical ser-
vice as indicated in this Owner’s
Manual and/or when made neces-
sary by mechanical conditions.
 Never operate a motorcycle with-
out proper training or instruction.
Take a training course. Beginners
should receive training from a cer-
tified instructor. Contact an autho-
rized motorcycle dealer to find out
about the training courses nearest
you.
Safe Ri din g
Perform the pre-operation checks
each time you use the vehicle to make
sure it is in safe operating condition.
Failure to inspect or maintain the vehi-
cle properly increases the possibility of an accident or equipment damage.
See page 5-1 for a list of pre-operation
checks.
 This motorcycle is designed for
off-road use only, therefore, it is il-
legal to operate it on public
streets, roads, or highways, even
a dirt or gravel one. Off-road use
on public lands may be illegal.
Please check local regulations be-
fore riding.
 This motorcycle is designed to
carry the operator only. No pas-
sengers.
 The failure of motorists to detect
and recognize motorcycles in traf-
fic is the predominating cause of
automobile/motorcycle accidents.
Many accidents have been
caused by an automobile driver
who did not see the motorcycle.
Making yourself conspicuous ap-
pears to be very effective in reduc-
ing the chance of this type of
accident.
Therefore:
• Wear a brightly colored jacket.
• Use extra caution when you are approaching and passing
through intersections, since in-
tersections are the most likely
places for motorcycle accidents
to occur.
• Ride where other motorists can see you. Avoid riding in another
motorist’s blind spot.
• Never maintain a motorcycle without proper knowledge.
Contact an authorized motorcy-
cle dealer to inform you on ba-

WARNING
EWA10882
Gasoline an d g asoline vapors are
extremely flamma ble. To avoi d fires
an d explosions an d to re duce the
risk of injury when refuelin g, follow
these instructions.
1. Before refueling, turn off the en- gine and be sure that no one is sit-
ting on the vehicle. Never refuel
while smoking, or while in the vi-
cinity of sparks, open flames, or
other sources of ignition such as
the pilot lights of water heaters
and clothes dryers.
2. Do not overfill the fuel tank. Stop filling when the fuel reaches the
bottom of the filler tube. Because
fuel expands when it heats up,
heat from the engine or the sun
can cause fuel to spill out of the
fuel tank.
3. Wipe up any spilled fuel immedi- ately. NOTICE: Immediately
wipe off spille d fuel with a clean,
d ry, soft cloth, since fuel may
d eteriorate painted surfaces or
plastic parts.

WARNING
EWA10201
Always blee d b oth fork le gs, other-
wise poor han dlin g an d loss of sta-
b ility may result.
When riding in extremely rough condi-
tions, the air temperature and pressure
in the front fork will rise. This will in-
crease the spring preload and harden
the front suspension. If this occurs,
bleed the front fork as follows.
1. Lift the front wheel off the ground according to the procedure on
page 7-28.
TIP
When bleeding the front fork, there
should be no weight on the front end of
the vehicle.
2. Remove the bleed screws and al-low all of the air to escape from
each fork leg.
3. Install the bleed screws.
4. Lower the front wheel so that it is on the ground, install the remov-
able sidestand, and then rest the
motorcycle on it.
