CAUTION:@ l
In order to prevent clutch slip-
page (since the engine oil also
lubricates the clutch), do not
mix any chemical additives with
the oil or use oils of a higher
grade than “CD”. In addition, do
not use oils labeled “ENERGY
CONSERVING II” or higher.
l
Make sure that no foreign mate-
rial enters the crankcase.
@9. Start the engine, and then let it idle
for several minutes while checking
it for oil leakage. If oil is leaking,
immediately turn the engine off
and check for the cause.
10. Turn the engine off, and then
check the oil level and correct it if
necessary.
EAU03495
Coolant The coolant level should be checked
before each ride. In addition, the cool-
ant must be changed at the intervals
specified in the periodic maintenance
and lubrication chart.
If the engine overheats, see page 6-45
for further instructions.
To check the coolant level
1. Place the motorcycle on a level
surface and hold it in an upright
position.NOTE:@ l
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
l
Make sure that the motorcycle is
positioned straight up when
checking the coolant level. A slight
tilt to the side can result in a false
reading.

7. Remove the coolant reservoir
bolts.
8. Slightly move the coolant reservoir
back, and then disconnect the
hose at the bottom of the coolant
reservoir.
9. Drain the coolant from the coolant
reservoir by opening the cap, then
turning the reservoir upside down.
10. Connect the hose to the coolant
reservoir.
11. Install the coolant reservoir by
placing it in the original position,
then installing the bolts.12. After the coolant is completely
drained, thoroughly flush the cool-
ing system with clean tap water.
13. Install the coolant drain bolts, and
then tighten them to the specified
torque.
NOTE:@ Check the washers for damage and re-
place them if necessary. @14. Pour the recommended coolant
into the radiator until it is full.

CAUTION:@ l
Apply spray oil and wax spar-
ingly and make sure to wipe off
any excess.
l
Never apply oil or wax to any
rubber and plastic parts, but
treat them with a suitable care
product.
l
Avoid using abrasive polishing
compounds as they will wear
away the paint.
@NOTE:@ Consult a Yamaha dealer for advice on
what products to use. @
Storage Short-term
Always store your motorcycle in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00014
CAUTION:@ l
Storing the motorcycle in a
poorly ventilated room or cover-
ing it with a tarp, while it is still
wet, will allow water and humid-
ity to seep in and cause rust.
l
To prevent corrosion, avoid
damp cellars, stables (because
of the presence of ammonia)
and areas where strong chemi-
cals are stored.
@
Long-term
Before storing your motorcycle for
several months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. For motorcycles equipped with a
fuel cock that has an “OFF” posi-
tion: Turn the fuel cock lever to
“OFF”.
3. Drain the carburetor float chamber
by loosening the drain bolt; this will
prevent fuel deposits from building
up. Pour the drained fuel into the
fuel tank.
4. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
5. Perform the following steps to pro-
tect the cylinders, piston rings, etc.
from corrosion.
