Brake light switch adjustmentThe rear brake light switch is activated
by the brake pedal and is properly ad-
justed when the brake light comes on
just before braking takes effect. To ad-
just the rear brake light switch, hold the
switch body so it does not rotate while
turning the adjusting nut.
Turn the adjusting nut in direction
a to
make the brake light come on earlier.
Turn the adjusting nut in direction
b to
make the brake light come on later.

Checking the front and rear
brake padsWear indicator grooves are provided
on each brake pad. These indicators
allow checking of brake pad wear with-
out disassembling the brake. Inspect
the grooves. If they have almost disap-
peared, ask a Yamaha dealer to re-
place the pads.

Rear wheel installation1. Apply a light coating of lithium
soap base grease to the final gear
case splines and the rear wheel
hub splines.
2. Install the wheel and the wheel ax-
le.
3. Install the caliper and caliper bolts.
Make sure there is enough gap
between the brake pads before in-
stalling the caliper onto the brake
disc.4. Install the brake torque rod bolt
and nut.
5. Install the pinch bolt and tighten it
to the specified torque.
6. Take the motorcycle off the cen-
terstand.
7. Tighten the axle nut, caliper bolts
and brake torque rod nut to the
specified torques.
8. Secure the brake torque rod nut
with a new cotter pin.

TroubleshootingAlthough Yamaha motorcycles receive
a rigid inspection before shipment from
the factory, trouble may occur during
operation.
Any problem in the fuel, compression,
or ignition systems can cause poor
starting and loss of power. The trouble-
shooting chart describes a quick, easy
procedure for making checks.
If your motorcycle requires any repair,
bring it to a Yamaha dealer. The skilled
technicians at a Yamaha dealership
have the tools, experience, and know-
how to properly service your motor-
cycle. Use only genuine Yamaha parts
on your motorcycle. Imitation parts may
look like Yamaha parts, but they are of-
ten inferior. Consequently, they have a
shorter service life and can lead to ex-
pensive repair bills.

Tightening torque:
Pinch bolt:
16 Nm (1.6 m·kg)
Axle nut:
105 Nm (10.5 m·kg)
Caliper bolt:
35 Nm (3.5 m·kg)
Brake torque rod nut:
23 Nm (2.3 m·kg)

CAUTION:@ l
Avoid using strong acidic wheel
cleaners, especially on spoked
wheels. If you do use such
products for hard-to-remove
dirt, do not leave it on any long-
er than instructed, then thor-
oughly rinse it off with water,
immediately dry the area and
apply a corrosion protection
spray.
l
Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or
sponge with mild detergent and
water to clean plastic.
l
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent or
thinner, fuel (gasoline), rust re-
movers or inhibitors, brake flu-
id, antifreeze or electrolyte.
l
Do not use high-pressure wash-
ers or steam-jet cleaners since
they cause water seepage and
deterioration in the following ar-
eas: seals (of wheel bearings,
swingarm bearings, forks and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
l
For motorcycles equipped with
a windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or
scratching. Some cleaning
compounds for plastic may
leave scratches on the wind-
shield. Test the product on a
small hidden part of the wind-
shield to make sure they do not
leave any marks. If the wind-
shield is scratched, use a quali-
ty plastic polishing compound
after washing.
@After riding in the rain, near the sea oron salt-sprayed roadsSince sea salt or salt sprayed on the
roads in the winter are extremely corro-
sive in combination with water, carry
out the following steps after each ride
in the rain, near the sea or on salt-
sprayed roads. (Salt sprayed in the
winter may remain on the roads well
into spring.)
