el is low. If this symbol flashes,
stop the engine immediately and
fill it with oil to the specified level.
l
The light will come on and symbol
“ ” will flash if the coolant tem-
perature is too high. The following
chart shows the conditions of the
indicator light, symbol and tem-
perature display in accordance to
coolant temperature.
The light circuit can be checked by the
procedure on page 3-5.

level, the indicator light may flicker
when riding on a slope or during sud-

CAUTION:@ The oil level/coolant temperature in-
dicator light and fuel indicator light
should come on for a few seconds
and then go off. If an indicator light
does not go off, refer to the corre-
sponding indicator light circuit
check in the “INSTRUMENT AND
CONTROL FUNCTIONS” section. @2. Shift the transmission into neutral.NOTE:@ When the transmission is in neutral, the
neutral indicator light should be on. If
the light does not come on, ask a
Yamaha dealer to inspect it. @3. Turn on the starter (choke) and
completely close the throttle grip.
4. Start the engine by pushing the
start switch.
NOTE:@ If the engine fails to start, release the
start switch, wait a few seconds, then
try again. Each attempt should be as
short as possible to preserve the bat-
tery. Do not crank the engine more
than 10 seconds on any one attempt. @5. After starting the engine, move the
starter (choke) to the halfway posi-
tion.NOTE:@ For maximum engine life, never accel-
erate hard with a cold engine! @6. After the engine is warm, turn off
the starter (choke) completely.NOTE:@ The engine is warm when it responds
normally to the throttle with the starter
(choke) turned off. @

Cooling system1. Check the coolant level in the res-
ervoir tank when the engine is cold
as the coolant level will vary with
engine temperature. The coolant
level should be between the maxi-
mum and minimum marks.2. If the level is low, remove the res-
ervoir tank cover by removing the
bolts.
3. Add coolant or distilled water to
raise it to the specified level.
4. Install the reservoir tank cover and
bolts.1. Maximum level mark

CAUTION:@ Hard water or salt water is harmful
to the engine. You may use distilled
water if you can’t get soft water. @NOTE:@ If water is added, have a Yamaha deal-
er check the antifreeze content of the
coolant as soon as possible.
The radiator fan operation is complete-
ly automatic. It is switched on or off ac-
cording to the coolant temperature in
the radiator. @5. If your motorcycle overheats, see
page 6-42 for details.

cowling B. (See page 6-6 for re-
moval and installation proce-
dures.)
2. Place a container under the en-
gine.
3. Remove the radiator cap.4. Remove the water pump drain bolt
and drain the coolant from the wa-
ter pump housing.
5. Disconnect the radiator hose by
loosening the clamp and drain the
coolant completely.
