1. Push the “SELECT 1” button for at
least two seconds to set the auto
start.TIP

When the stopwatch is set to auto start,
the stopwatch indicator “ ” and the
distance-compensation tripmeter indi-
cator “ ” will start flashing, and the
digits in the display will start scrolling
from left to right.2. When the vehicle starts moving,

when the vehicle is stopped. To stop
and/or resume counting, repeat steps 3
and 4.
Measurement mode (for calibrating
the distance-compensation tripme-
ter’s reading)
The distance-compensation tripmeter
is a feature intended to provide a more
accurate tripmeter reading for enduro
riding. Calibrating this meter in accor-
dance with the distances specified on
the enduro course map will help famil-
iarize the rider with the course. In addi-
tion, calibrating the meter may also be
necessary when using tire, wheel,
chain sprocket sizes, etc. other than
specified. For further information con-
cerning the use of this meter, please
consult your nearby Yamaha dealer.
Calibrate the distance-compensation
tripmeter as follows.
To increase the reading, push the
“SELECT 1” button. To decrease the
reading, push the “SELECT 2” button.
Pushing and holding either button will
increase or decrease the reading con-
tinuously until the button is released.
TIP

Calibrating the reading of the dis-
tance-compensation tripmeter is possi-
ble regardless of the stopwatch

Changing the brake fluid
Have a Yamaha dealer change the
brake fluid at the intervals specified in
the TIP after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the master cylinders and
calipers as well as the brake hoses re-
placed at the intervals listed below or
whenever they are damaged or leak-
ing.

Oil seals: Replace every two
years.

Brake hoses: Replace every four
years.
EAU22760
Drive chain slack
The drive chain slack should be
checked before each ride and adjusted
if necessary.
EAU47221
To check the drive chain slack
1. Place the motorcycle on the side-
stand.
TIP

When checking and adjusting the drive
chain slack, there should be no weight
on the motorcycle.
2. Shift the transmission into the neu-
tral position.
3. Push on the drive chain at the cen-
ter point between the chain ten-
sioner and the chain support
mounting bolt with a force of 50 N
(5.0 kgf, 36 lbf).
4. Measure drive chain slack be-
tween the swingarm and the top of
the chain link closest to the swing-
arm as shown.5. If the drive chain slack is incorrect,
adjust it as follows.
EAU22943
To adjust the drive chain slack
1. Loosen the axle nut and the lock-
nut on each side of the swingarm.
2. To tighten the drive chain, turn the
drive chain slack adjusting bolt on
each side of the swingarm in direc-
tion (a). To loosen the drive chain,
turn the adjusting bolt on each side
of the swingarm in direction (b),
and then push the rear wheel for-
ward.

of the motorcycle and can lead
to chain slippage or breakage.
To prevent this from occurring,
keep the drive chain slack with-
in the specified limits.

TIP

Using the alignment marks on each
side of the swingarm, make sure that
both chain pullers are in the same posi-
tion for proper wheel alignment.
3. Tighten the locknuts, and then
tighten the axle nut to the specified
torque.
EAU23023
Cleaning and lubricating the
drive chain
The drive chain must be cleaned and
lubricated at the intervals specified in
the periodic maintenance and lubrica-
tion chart, otherwise it will quickly wear
out, especially when riding in dusty or
wet areas. Service the drive chain as
follows.
NOTICE

ECA10581
The drive chain must be lubricated
after washing the motorcycle and
riding in the rain.
1. Clean the drive chain with kero-
sene and a small soft brush.
NOTICE:
To prevent damaging
the O-rings, do not clean the
drive chain with steam cleaners,
high-pressure washers or inap-
propriate solvents.

[ECA11121]

2. Wipe the drive chain dry.
3. Thoroughly lubricate the drive
chain with a special O-ring chain
lubricant.
NOTICE:
Do not use

EAU25871
Troubleshooting
Although Yamaha motorcycles receive
a thorough inspection before shipment
from the factory, trouble may occur dur-
ing 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 inferi-
or, have a shorter service life and can
lead to expensive repair bills.
WARNING

EWA15141
When checking the fuel system, do
not smoke, and make sure there are
no open flames or sparks in the ar-
ea, including pilot lights from water
