8. Install the tailpipe cover bolts and tightenthem to the specified torque.EBU32460Valve clearanceThe correct valve clearance changes with
use, resulting in improper fuel/air supply or
engine noise. To preven t this, the valve clear-
ance must be adjusted regularly. This adjust-
ment however, should be left to a
professional Yamaha service technician.EBU32470BrakesReplacement of brake components requires
professional knowledge. Brake service
should be performed by a Yamaha dealer.
WARNING
EWB02572Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident. EBU35150Checking the front and rear brake padsCheck each brake pad for damage and mea-
sure the lining thickness. If a brake pad is
damaged or if the lining thickness is less than
1.0 mm (0.04 in), have a Yamaha dealer re-
place the brake pads as a set.
The wheels need to be removed to check the
brake pads. (See page s 9-56, 9-58 for wheel
removal and installation procedures.)
Tightening torque: Tailpipe cover bolt:8 N·m (0.8 kgf·m, 5.9 lb·ft)

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 leakage; 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.EBU35182Checking 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.
