Periodic maintenance and lubrication chartNOTE:● ●● ●
●
The annual checks must be performed every year, except if a kilometer-based maintenance, or for the UK, a
mileage-based maintenance, is performed instead.
●
From 30000 km (17500 mi), repeat the maintenance intervals starting from 6000 km (3500 mi).
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and techni-
cal skills.

Checking the spark plugThe spark plug is an important engine
component, which is easy to check.
Since heat and deposits will cause any
spark plug to slowly erode, the spark
plug should be removed and checked
in accordance with the periodic main-
tenance and lubrication chart. In addi-
tion, the condition of the spark plug can
reveal the condition of the engine.
To remove the spark plug
1. Remove panel A. (See page 6-5.)
2. Remove the spark plug cap.ZAUM00**

1. Spark plug wrench
Spark plug, checking
3. Remove the spark plug as shown,
with a spark plug wrench available
at a Yamaha dealer.
To check the spark plug
1. Check that the porcelain insulator
around the center electrode of the
spark plug is a medium-to-light tan
(the ideal color when the vehicle is
ridden normally).
NOTE:
If the spark plug shows a distinctly dif-
ferent color, the engine could be oper-
ating improperly. Do not attempt to di-
agnose such problems yourself. In-
stead, have a Yamaha dealer check the
vehicle.2. Check the spark plug for electrode
erosion and excessive carbon or
other deposits, and replace it if
necessary.Specified spark plug:

To install the spark plug
1. Measure the spark plug gap with a
wire thickness gauge and, if nec-
essary, adjust the gap to specifi-
cation.Spark plug gap:
0.7 ~ 0.8 mm (0.028 ~ 0.031 in)2. Clean the surface of the spark plug
gasket and its mating surface, and
then wipe off any grime from the
spark plug threads.
3. Install the spark plug with the spark
plug wrench, and then tighten it to
the specified torque.Tightening torque:
Spark plug:
NOTE:
If a torque wrench is not available when
installing a spark plug, a good estimate
of the correct torque is 1/4~1/2 turn past
finger tight. However, the spark plug
should be tightened to the specified
torque as soon as possible.
4. Install the spark plug cap.
5. Install the panel.

Engine oil and oil strainerThe engine oil level should be checked
before each ride. In addition, the oil must
be changed and the oil strainer cleaned
at the intervals specified in the periodic
maintenance and lubrication chart.
To check the engine oil level
1. Place the vehicle on the
centerstand.NOTE:
Make sure that the vehicle is positioned
straight up when checking the oil level.
A slight tilt to the side can result in a
false reading.2. Start the engine, warm it up for sev-
eral minutes, and then turn it off. Engine oil

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.NOTE:
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 and clean
the oil strainer
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 bolts A and B
to drain the oil from 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 neces-
sary.

Final transmission oilThe final transmission case must be
checked for oil leakage before each ride.
If any leakage is found, have a Yamaha
dealer check and repair the scooter. In
addition, the final transmission oil must
be changed as follows at the intervals
specified in the periodic maintenance
and lubrication chart.
1. Start the engine, warm it up by
riding the scooter for several min-
utes, and then stop the engine.
2. Place the scooter on the
centerstand.

transmission case to collect the
used oil. Final transmission oil

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.NOTE:●
The coolant level must be checked
on a cold engine since the level
varies with engine temperature.
●
Make 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.

●
If coolant is not available, use
distilled water or soft tap water
instead. Do not use hard water
or salt water since it is harmful
to the engine.
● ●● ●
●
If water has been used instead
of coolant, replace it with cool-
ant as soon as possible, other-
wise the cooling system will not
be protected against frost and
corrosion.

●
If water has been added to the
coolant, have a Yamaha dealer
check the antifreeze content of
the coolant as soon as possible,otherwise the effectiveness of
the coolant will be reduced.
