EAU00423Shifting
The transmission lets you control the
amount of power you have available
at a given speed for starting, acceler-
ating, climbing hills, etc. The use of
the shift pedal is shown in the illustra-
tion.
To shift into neutral, depress the shift
pedal repeatedly until it reaches the
end of its travel, then raise the pedal
slightly.

Do not coast for long periods
with the engine off, and do not
tow the motorcycle a long dis-
tance. Even with gears in neu-
tral, the transmission is only
properly lubricated when the
engine is running. Inadequate
lubrication may damage the
transmission.
8 8
Always use the clutch when
changing gears. The engine,
transmission, and driveline are
not designed to withstand the
shock of forced shifting and
can be damaged by shifting
without using the clutch.

5. Engine overheating
w
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 counterclock-
wise 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 rec-
ommended coolant as soon as possible.
Level is OK.
Wait until the engine
has cooled.
Restart the engine. If the engine overheats again, ask a
Yamaha dealer to inspect and repair the cooling system. Check the coolant level in the
reservoir tank and/or radiator.
Add coolant (See NOTE.)
Level is low, check thecooling system for leakage.Leakage.No
leakage.Ask a Yamaha dealer to inspect
and repair the cooling system.
