Inspecting the brake fluid
levelInsufficient brake fluid may let air enter
the brake system, possibly causing the
brakes to become ineffective.
Before riding, check that the brake fluid
is above the minimum level and replen-
ish when necessary.
Observe these precautions:l
When checking the fluid level,
make sure the top of the master
cylinder is level by turning the han-
dlebars.
l
Use only the designated quality
brake fluid. Otherwise, the rubber
seals may deteriorate, causing
leakage and poor brake perfor-
mance.
l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor brake performance.
l
Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
Have a Yamaha dealer check the
cause if the brake fluid level goes
down.

Drive chain slack adjustment1. Loosen the axle nut.
2. Loosen the locknuts on each side.
To tighten the chain, turn the chain
adjusting bolts in direction
a. To
loosen the chain, turn the adjust-
ing bolts in direction
b and push
the wheel forward. Turn each ad-
justing bolt exactly the same
amount to maintain correct axle
alignment. There are marks on
each side of the swingarm. Use
these marks to align the rear
wheel.
EC000096
CAUTION:@ Too little chain slack will overload
the engine and other vital parts.
Keep the slack within the specified
limits. @3. After adjusting, tighten the lock-
nuts. Then tighten the axle nut to
the specified torque.
EAU03006
Drive chain lubricationThe chain consists of many parts which
work with each other. If the chain is not
maintained properly, it will wear out
quickly. Therefore, the chain must be
serviced regularly. This service is es-
pecially necessary when riding in dusty
areas. This motorcycle is equipped
with a sealed type chain. Steam clean-
ing, high-pressure washers, and sol-
vents can damage the drive chain, so
do not use these for cleaning it. Use
only kerosene to clean the drive chain.
Wipe it dry, and thoroughly lubricate it
with SAE 30 ~ 50W motor oil. Do not
use any other lubricants on the drive
chain. They may contain solvents that
could damage the sealed chain.
EC000097
CAUTION:@ Be sure to oil the chain after wash-
ing the motorcycle or riding in the
rain. @

EW000070
WARNING
@ Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be blown
out under pressure, which could cause serious injury. Open the radiator cap as follows. Wait until the engine has
cooled. Remove the radiator cap stopper by removing the screw. Place a thick rag like a towel over the radiator cap
and slowly rotate the cap counterclockwise to the detent. This procedure allows any residual pressure to escape.
When the hissing sound has stopped, press down on the cap while turning counterclockwise and remove it. @NOTE:@ If it is difficult to get the recommended coolant, tap water can be temporarily used, provided that it is changed to the recom-
mended coolant as soon as possible. @
Wait until the
engine has cooled.
Check the coolant level in the
reservoir tank 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 NOTE.)
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system.
