4-2 NOTE:
Pre-operation checks should be made each time the motorcycle is used. Such an inspection can be thoroughly accomplished
in a very short time; and the added safety it assures is more than worth the time involved. If any maintenance service or
adjustment is needed, consult the chart above to refer to the pages in which the service or adjustment is described.
1. The engine, exhaust pipe, and muffler will be very hot after the engine has been run.
Be careful not to touch them or to allow any clothing item to contact them during inspection or repair.
2. If any item is not working properly, have it inspected and repaired before operating the motorcycle.

4-3 Brakes (See page 6-17 for details)
1. Brake lever and brake pedal
Check for correct free play in the front brake lever and
rear brake pedal and adjust if necessary. Make sure
the brakes are working properly by checking at low
speed shortly after starting out.
A soft, spongy feeling in the brake lever indicates a
failure in the brake system. Do not operate the
motorcycle until the failure in the brake system is
corrected. Ask a Yamaha dealer or other qualified
mechanic for immediate repairs. A soft, spongy feeling
could indicate a hazardous condition in the brake
system.
NOTE:
If DOT #4 is not available, #3 can be used.
3. Check the disc pads.
Refer to page 6-20
4. Check the brake shoes.
Refer to page 6-20
When a brake service is necessary, consult a Yamaha
dealer or other qualified mechanic.
NOTE:
2. Brake fluid
Check the brake fluid level. Add fluid if necessary.
RECOMMENDED BRAKE FLUID: DOT #4

4-5 Tires
To ensure maximum performance, long service, and safe
operation, note the following:
1. Tire air pressure
Always check and adjust the tire pressure before
operating the machine.
Tire inflation pressure should be checked and adjusted
when the temperature of the tire equals the ambient air
temperature.
Tire inflation pressure must be adjusted according to
total weight of cargo, rider, passenger and accessories
(fairing, saddlebags, etc. if approved for this model),
and vehicle speed.

4-6 Proper loading of your motorcycle is important for the
handling, braking, and other performance and safety
characteristics of your motorcyle. Do not carry loosely
packed items that can shift. Securely pack your heaviest
items close to the center of the motorcycle, and
distribute the weight evenly from side to side. Properly
adjust the suspension for your load, and check the
condition and pressure of your tires. NEVER
OVERLOAD YOUR MOTORCYCLE. Make sure the total
weight of the cargo, rider, passenger, and accessories
(fairing, saddlebags, etc. if approved for this model)
does not exceed the maximum load of the motorcycle.
Operation of an overloaded motorcycle could cause tire
damage, an accident, or even injury.
2. Tire inspection
Always check the tires before operating the motorcycle.
If a tire tread shows crosswise lines (minimum tread
depth), if the tire has a nail or glass fragments in it, or if
the side wall is cracked, contact a Yamaha dealer or
other qualified mechanic and have the tire replaced.

4-8Wheels
To ensure maximum performance, long service, and safe
operation, note the following:
1. Always inspect the wheels before a ride. Check for
cracks, bends, or warpage of the wheel; be sure the
spokes are tight and undamaged. If any abnormal
condition exists in a wheel, consult a Yamaha dealer or
other qualified mechanic. Do not attempt even small
repairs to the wheel. If a wheel is deformed or cracked,
it must be replaced.
2. Tires and wheels should be balanced whenever either
one is changed or replaced. Failure to have a wheel
balanced can result in poor performance, adverse
handling characteristics, and shortened tire life.
3. After installing a tire, ride conservatively to allow the
tire to seat itself on the rim properly. Failure to allow
proper seating may cause tire failure, resulting in
damage to the motorcycle and injury to the rider. Clutch ( See page 6-16 for details)
Check the free play in the clutch lever, and make sure the
lever operates properly. If the free play is incorrect, adjust
it.
Throttle grip (See page 6-14 for details)
Turn the throttle grip to see if it operates properly, and check
the free play.
Make sure the grip returns by spring force when released.
Ask a Yamaha dealer or other qualified mechanic to make
any necessary adjustments.
Fitting/Fasteners
Alway check the tightness of chassis fittings and fasteners
before a ride. Use the chart on page 6-5 to find the correct
torque.
Switches
Check the operation of the starter switch, main switch,
“Engine Stop” switch.

CAUTION:
Always wipe off spilled fuel immediately with a dry and

or plastic parts.
Fuel
-.  / -  .0
Make sure there is sufficient fuel in the tank.
Do not overfill the fuel tank. Avoid spilling fuel on the
hot engine. Do not fill the fuel tank above the bottom of
the filler tube as shown in the illustration or it may
overflow when the fuel heats up later and expands.

Your Yamaha engine has been designed to use regular
unleaded gasoline with a pump octane number ([R+m]/2)
of 86 or higher, or research octane number of 91 or higher.
If knocking or pinging occurs, use a different brand of
gasoline or premium unleaded fuel. Unleaded fuel will give
you longer spark plug life and reduced maintenance cost.
If unleaded gasoline is not available, then leaded regular
gasoline can be used.
Gasohol
There are two types of gasohol; gasohol containing ethanol
and that containing methanol. Gasohol containing ethanol
can be used if ethanol content does not exceed 10%.
Gasohol containing methanol is not recommended by
Yamaha because it can cause fuel system damage or
vehicle performance problems.

CAUTION:
Before riding this motorcycle, become thoroughly
familiar with all operating controls and their functions.
Consult a Yamaha dealer regarding any control or
function that you do not thoroughly understand.
Never start your engine or let it run for any
length of time in a closed area.
The exhaust fumes are poisonous and can cause loss
of consciousness and death within a short time. Always
operate your machine in an area with adequate
ventilation.
