settles, remove the oil filler cap,
wipe the dipstick clean, insert it
back into the oil filler hole (without
screwing it in), and then remove it
again to check the oil level.TIP
The engine oil should be between the
minimum and maximum level marks.4. If the engine oil is below the mini-
mum level mark, add sufficient oil
of the recommended type to raise
it to the correct level.
5. Insert the dipstick into the oil filler
hole, and then tighten the oil filler
cap.
To change the engine oil
1. Start the engine, warm it up for sev-
eral minutes, and then turn it off.
2. Place an oil pan under the engine
to collect the used oil.3. Remove the engine oil filler cap and
the engine oil drain bolt to drain the

EAUT1523
To check the coolant level
The coolant level should be checked as
follows before each ride. In addition, the
coolant must be changed at the inter-
vals specified in the periodic mainte-
nance and lubrication chart.
1. Place the vehicle on the
centerstand.TIP
8The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
8Make sure that the vehicle is posi-
tioned straight up when checking
the coolant level. A slight tilt to the
side can result in a false reading.
2. Check the coolant level in the cool-
ant reservoir.TIP
The coolant should be between the mini-
mum and maximum level marks.ZAUM00**

coolant reservoir cap. Never at-
tempt to remove the radiator cap
when the engine is hot.
[EWA15161]
4. Add coolant or distilled water to
raise the coolant to the maximum
level mark, and install the coolant
reservoir cap and the panel.
NOTICE:
If coolant is not avail-
able, use distilled water or soft
tap water instead. Do not use hard
water or salt water since it isharmful to the engine. If water
has been used instead of cool-
ant, replace it with coolant as
soon as possible, otherwise the
cooling system will not be pro-
tected against frost and corro-
sion. If water has been added to
the coolant, have a Yamaha
dealer check the antifreeze con-
tent of the coolant as soon as
possible, otherwise the effective-
ness of the coolant will be
reduced.

Cast wheelsTo maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points regard-
ing the specified wheels.●
The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked
wheel must be replaced.
●
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
●
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics. Wheels
