EBU33706Engine oil and oil filter cartridgeCheck the engine oil level before each opera-
tion. In addition, change the oil and the oil fil-
ter cartridge at the intervals specified in the
periodic maintenance chart.NOTICEECB00301 In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do
not use oils with a diesel specification of
“CD” or oils of a higher quality than
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or
higher. 
Make sure that no foreign material en-
ters the crankcase.
To check the engine oil level
1. Park the vehicle on a level surface.
2. Check the engine oil level on a cold en-
gine.TIPIf the engine was started before checking the
oil level, be sure to warm up the engine suffi-
ciently, and then wait at least 10 minutes until
the oil settles for an accurate reading. 3. Remove the passenger seat cushion.(See page 4-15.)
4. Remove the rubber cover.
Recommended engine oil: See page 10-1.
Oil quantity: Oil change only:2.20 L (2.33 US qt, 1.94 Imp.qt)
When replacing the filter: 2.30 L (2.43 US qt, 2.02 Imp.qt)

EBU33691V-belt case drain plugThe V-belt case drain plug is located behind
the left panel. (See page 8-11 for left panel re-
moval and installation procedures.)
After operating in water deep enough to allow
water to enter the V-belt case, remove the
drain plug to drain any water from the case.
If water drains from the V-belt case after re-
moving the drain plug, have a Yamaha dealer
inspect the vehicle, as the water may affect
other engine parts.
EBU32450Cleaning the spark arrester
WARNING
EWB03370Hot exhaust system may cause burns. To
avoid burns or fires, make sure that the en-
gine is stopped and the exhaust system is
cool before cleaning the spark arrester. Do
not start the engine while cleaning the ex-
haust system. 1. Remove the tailpipe bolts.

EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To prevent this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.
EBU32480Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indi-
cator grooves have almost disappeared, have
a Yamaha dealer replace the brake pads as a
set.
The wheels need to be removed to check the
brake pads. (See pages 8-45, 8-47 for wheel
removal and installation procedures.)

Clean the filler cap before removing. Use
only DOT 4 brake fluid from a sealed
container.
 Use only the specified brake fluid; other-
wise, the rubber seals may deteriorate,
causing leakage.
 Refill with the same type of brake fluid.
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
 Be careful that water does not enter the
brake fluid reservoir when refilling. Wa-
ter will significantly lower the boiling
point of the fluid and may result in vapor
lock. NOTICEECB01161Brake fluid may damage painted surfaces
or plastic parts. Always clean up spilled
fluid immediately.
As the brake pads wear, it is normal for the
brake fluid level to gradually go down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check and repair the vehicle before
any further operation.EBU32520Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.
Replace the oil seals every two years.
 Replace the brake hoses every four years.

get prompt medical attention.
WARNING
EWB03420Batteries may produce explosive gases.
Ventilate when charging or using in a
closed space. Keep batteries away from
sparks, flames, cigarettes, or other sourc-
es of ignition. To remove the battery1. Turn the key to “ ” (off).
2. Remove the hood. (See page 8-10.)
3. Remove the air intake duct panel by re- moving the quick fastener screws. 4. Disconnect the negative battery lead first,
then the positive battery lead. NOTICE:
When removing the battery, the main
switch must be of f, and the negative
lead must be disconnected before the
positive lead.

3. Disconnect the headlight coupler.
4. Unhook the headlight bulb holder.5. Wait for the headlight bulb to cool before
touching or removing it. Remove the
burnt-out bulb by pulling it out.
6. Place a new headlight bulb into position, and then secure it with the bulb holder.
NOTICE: Do not touch the glass part of
the bulb. Oil from your fingers or other
contamination will adversely affect the
transparency of the glass, luminosity
of the bulb, and bulb life. Thoroughly1. Headlight bulb cover

Engine overheating
Wait for the engine to cool before removing the radiator cap. WARNING! If the engine is not
cool when removing the radiator cap, hot fluid and steam could blow out under pressure
and burn you.
[EWB03460]
Place a thick rag over the cap and remove the cap slowly to allow any re-
maining pressure to escape.
TIP Tap water can be used in an emergency. Change to the recommended coolant as soon as
possible.
 The engine will tend to overheat if the radiator is caked with mud, or if air was not properly bled
from the cooling system. Wait until the
engine has cooled.
Check the coolant le vel in the
coolant reservoir and/or radiator.
Level is OK.Level is low, check the
cooling system for leakage.
No
leakage.Leakage.
Ask a Yamaha dealer to inspect
and repair the cooling system.Add coolant. (See TIP.)
Restart the engine. If the engine o verheats again, ask a
Yamaha dealer to inspect and/or repair the cooling system.

4. Once the majority of the dirt has beenhosed off, wash all surfaces with warm
water and mild, detergent-type soap. An
old toothbrush or bottle brush is handy
for hard-to-get-at places.
5. Rinse the vehicle off immediately with clean water and dry all surfaces with a
clean chamois towel or soft, absorbent
cloth.
6. Clean the seats with a vinyl upholstery cleaner to keep the covers pliable and
glossy.
7. Automotive-type wax may be applied to all painted and chrome-plated surfaces.
Avoid combination cleaner-waxes. Many
contain abrasives which may scratch the
paint or protective finish. When finished,
start the engine and let it idle for several
minutes.
EBU36120StorageLong term storage (60 days or more) of your
vehicle will require some preventive proce-
dures to guard against deterioration. Make
any necessary repairs before storing the vehi-
cle.
After thoroughly cleaning the vehicle, prepare
for storage as follows:
1. Fill the fuel tank with fresh fuel and add the specified amount of Fuel Med Rx or
another high-quality fuel stabilizer prod-
uct. Follow the instructions on the prod-
uct label. Operate the vehicle for at least
5 minutes to distribute treated fuel
through the fuel system.
2. Remove the spark plug and pour one ta- blespoon of fresh engine oil into the cyl-
inder and then re-install the spark plug.Specified amount:1 oz of stabilizer to each gallon of fuel (or
7.5 ml of stabilizer to each liter of fuel)
