to prevent the discharging of fuel vapor
into the atmosphere. Before operating
this vehicle, make sure to check the
following:
 Check each hose connection.
 Check each hose and canister for
cracks or damage. Replace if
damaged.
 Make sure that the canister
breather is not blocked, and if
necessary, clean it.

Engine oilThe engine oil level should be checked
regularly. In addition, the oil must be
changed and the oil filter cartridge re-
placed at the intervals specified in the
periodic maintenance chart.NOTICE
ECA11621
 In or der to prevent clutch slip-
pa ge (since the en gine oil also
lu bricates the clutch), do not
mix any chemical additives. Do
not use oils with a diesel speci-
fication of “CD” or oils of a hi gh-
er quality than specifie d. In
a ddition, do not use oils la beled
“ENERGY CONSERVING II” or
hi gher.
 Make sure that no forei gn mate-
rial enters the crankcase.
To check the en gine oil level
1. After warming up the engine, wait a few minutes for the oil level to
settle for an accurate reading.
2. With the vehicle on a level surface, hold it upright for an accurate
reading.
3. Look at the check window located at the bottom-right side of the
crankcase.TIPThe engine oil should be between the
minimum and maximum level marks.

Brake li ght switchesThe brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Brake flui d may d amage painte d
surfaces or plastic parts. Always
clean up spille d flui d imme diately.As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate 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 the cause before
further riding.

gin g the brake flui dHave a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.

Drive chain slackThe drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU92611
To check the d rive chain slack
1. Place the motorcycle on the cen- terstand.
2. Shift the transmission into the neutral position.
3. Find the center point of the chain (position B) by measuring (approx.
53 mm (2.09 in)) forward from the
edge of the drive chain guard as
shown. 4. Push down on the center of the
drive chain and measure the dis-
tance A from the drive chain guard
to the middle of the chain link be-
ing pressed down at position B.
5. If distance A is incorrect, adjust it as follows. NOTICE: Improper
d rive chain slack will overload
the en gine as well as other vital
parts of the motorcycle an d can
lea d to chain slippag e or break-
a g e. If distance A is more than
55.0 mm (2.17 in), the chain can
d amag e the frame, swin garm, an
d other parts. To prevent this
from occurrin g, keep the drive
chain slack within the specifie d
limits.
[ECA23070]
EAU92600
To adjust the drive chain slack
Consult a Yamaha dealer before ad-
justing the drive chain slack. 1. Take the motorcycle off the cen- terstand, and then put the side-
stand down.
2. Loosen the axle nut and the lock- nut on each side of the swingarm.

position for proper wheel alignment.
5. Take the motorcycle off the cen-terstand, and then put the side-
stand down.
6. Tighten the axle nut, then the lock- nuts to their specified torques.

lubricated at the intervals specified in
the periodic maintenance and lubrica-

Trou bleshootin gAlthough Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition systems,
for example, can cause poor starting
and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your motorcycle
require any repair, take it to a Yamaha
dealer, whose skilled technicians have
the necessary tools, experience, and
know-how to service the motorcycle
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.
