TIPIf a torque wrench is not available when in-
stalling the spark plug, a good estimate of the
correct torque is 1/4–1/2 turn past finger tight.
However, the spark plug should be tightened
to the specified torque as soon as possible. NOTICEECB02900Do not use any tools to remove or install
the spark plug cap, otherwise the ignition
coil coupler may be damaged. The spark
plug cap may be difficult to remove be-
cause the rubber seal on the end of the cap
fits tightly. To remove the spark plug cap,
simply twist it back and forth while pulling
it out; to install it, twist it back and forth
while pushing it in.
EBU35423Air filter maintenanceThis model is equipped with two air filter ele-
ments, a primary foam-type air filter and a
secondary paper-type air filter.
The primary air filter is easily accessed and
should be cleaned and oiled every 300–600
km (200–400 mi).
The secondary air filter is more difficult to ac-
cess, cannot be cleaned, and should be re-
placed by a Yamaha dealer every 2000–5000
km (1200–3000 mi).1. Primary air filter

10. Thoroughly apply Yamalube foam air fil-ter oil (or other quality liquid foam air fil-
ter—do not use a spray-type product) to
the foam material. The foam air filter ele-
ment should be wet but not dripping.
11. Pull the foam air filter element over its frame.
12. Install the air filter.
13. Install the air filter case cover and lock it
into place by turning the air filter case
cover lock clockwise.
TIPMake sure that the match mark on the cover
lock is aligned with the close match mark on
the air filter case cover. 14. Install the panel.EBU35130Cleaning the air filter case check hosesThere is a check hose on each side of the air
filter case. If dust or water collects in a check
hose, empty the hose and clean the air filter
element and air filter case.1. Match mark

Be careful that water or dust does not
enter the brake or clutch fluid reservoir
when refilling. Water 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 or brake system l eakage; therefore, be
sure to check the brake pads for wear and the
brake system for leakage. A low clutch fluid
level may indicate clutch system leakage;
therefore, be sure to check the clutch system
for leakage. If the brake or clutch fluid level
goes down suddenly, have a Yamaha dealer
check and repair the vehicle before any fur-
ther operation.
EBU35170Brake and clutch 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 and clutch hoses every
four years.EBU35181Checking the clutch pedalThe clutch pedal should operate smoothly
and spring back to position when released.
When depressed, it should offer resistance
before reaching the floorboard. If the pedal
offers little resistance when depressed, or if
the transmission grinds gears when shifting,
have a Yamaha dealer check the vehicle.

EBU35230BatteryThe battery is located under panel A. (See
page 8-10.)
This model is equipped with a VRLA (Valve
Regulated Lead Acid) battery. There is no
need to check the electrolyte or to add dis-
tilled water. However, the battery lead con-
nections need to be checked and, if
necessary, tightened.
WARNING
EWB03410Avoid battery contact with skin, eyes, or
clothing. Shield eyes when working near
batteries. Keep out of reach of children.
You could be poisoned or severely burnedby the sulfuric acid in battery electrolyte. In
case of accidental contact with battery
electrolyte:
EXTERNAL: Flush with water.
INTERNAL: Drink large quantities of water
or milk. Follow with milk of magnesia,
beaten egg, or vegetable oil. Get prompt
medical attention.
EYES: Flush with water for 15 minutes and
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 battery
1. Turn the key to “ ” (off).
2. Remove panel A. (See page 8-10.)
