EBU38000FuelMake sure there is sufficient gasoline in the tank
before starting off. Refuel if necessary. (See page
5-20.)EBU19561Engine oilMake sure that the engine oil is at the specified
level. Add oil as necessary. (See page 9-20.)EBU19591Final gear oilMake sure that the final gear oil is at the specified
level. Add oil as necessary. (See page 9-25.)EBU19601Differential gear oilMake sure that the differential gear oil is at the
specified level. Add oil as necessary. (See page
9-27.)EBU19632CoolantMake sure that the coolant is at the specified level.
Add coolant as necessary. (See page 9-29.)
TIPThe coolant level must be checked on a cold en-
gine since the level varies with engine tempera-
ture. EBU29083Front and rear brakesBrake levers and brake pedal
Check that there is no free play in the front and
rear brake levers. If there is free play, have a
Yamaha dealer check the brake system.
Check for correct free play in the brake pedal. If
the free play is incorrect, adjust it. (See page
9-47.)
Check the operation of the brake levers and
pedal. They should move smoothly and there
should be a firm feeling when the brakes are ap-
plied. If not, have a Yamaha dealer check the
brake system.
Brake fluid level
Check the brake fluid level. Add fluid if necessary.
(See page 9-44.)

Brake fluid leakage
Check to see if any brake fluid is leaking out of the
pipe joints or brake fluid reservoirs. Apply the
brakes firmly for one minute. If a lever moves
slowly inward, there may be a leak in the brake
system. If there is any leakage, the brake system
should be checked by a Yamaha dealer.
Brake operation
Test the brakes at slow speed after starting out to
make sure they are working properly. If the brakes
do not provide proper braking performance,
check the brake pads for wear. (See page 9-43.)
EBU19762Throttle leverCheck the operation of the throttle lever. It must
open smoothly and spring back to the idle position
when released. Have a Yamaha dealer correct if
necessary.
EBU38062TiresCheck and adjust the tire pressure before each
ride. Check tires for wear and damage.
Tire pressure
A low-pressure tire gauge is included as standard
equipment. Make two measurements of the tire
pressure and use the second reading. Dust or dirt
in the gauge could cause the first reading to be in-
correct.
Specified brake fluid:
DOT 41. Low-pressure tire gauge
2. Tire air valve

6Tire pressure must be checked and set when the
tires are cold. The tire pressure should be the
same on both sides, and must be adjusted ac-
cording to vehicle loading conditions. Set the tire
pressure as specified below.
WARNING! Opera-
tion of this vehicle with improper tire pressure
may cause severe injury or death from loss of
control or rollover. Tire pressure below the
minimum specified could also cause the tire to
dislodge from the rim under severe driving
conditions.
