Periodic maintenance and lubrication chart
NOTE:
The annual checks must be performed every year, except if a kilometer-based maintenance is performed
instead.
From 50000 km, repeat the maintenance intervals starting from 10000 km.
Items marked with an asterisk should be performed by a Yamaha dealer as they require special tools, data and
technical skills.

Troubleshooting
Although Yamaha scooters receive a
thorough inspection before shipment
from the factory, trouble may occur
during operation. Any problem in the
fuel, compression, or ignition sys-
tems, for example, can cause poor
starting and loss of power.
The following troubleshooting charts
represent quick and easy procedures
for checking these vital systems your-
self. However, should your scooter
require any repair, take it to a Yamaha
dealer, whose skilled technicians
have the necessary tools, experience,
and know-how to service the scooter
properly.
Use only genuine Yamaha replace-
ment parts. Imitation parts may look
like Yamaha parts, but they are often
inferior, have a shorter service life and
can lead to expensive repair bills.

Care
While the open design of a scooter
reveals the attractiveness of the tech-
nology, it also makes it more vulnera-
ble. Rust and corrosion can develop
even if high-quality components are
used. A rusty exhaust pipe may go
unnoticed on a car, however, it
detracts from the overall appearance
of a scooter. Frequent and proper
care does not only comply with the
terms of the warranty, but it will also
keep your scooter looking good,
extend its life and optimize its perfor-
mance.
Before cleaning
1. Cover the muffler outlet with a
plastic bag after the engine has
cooled down.
2. Make sure that all caps and
covers as well as all electrical
couplers and connectors, inclu-
ding the spark plug cap, are
tightly installed.
3. Remove extremely stubborn dirt,
like oil burnt onto the crankcase,
with a degreasing agent and a
brush, but never apply such pro-ducts onto seals, gaskets and
wheel axles. Always rinse the dirt
and degreaser off with water.
Cleaning
ECA10780
CAUTION
Avoid using strong acidic whe-
el cleaners, especially on spo-
ked wheels. If such products
are used on hard-to-remove
dirt, do not leave the cleaner on
the affected area any longer
than instructed. Also, tho-
roughly rinse the area off with
water, immediately dry it, and
then apply a corrosion protec-
tion spray.
Improper cleaning can damage
windshields, cowlings, panels
and other plastic parts. Use
only a soft, clean cloth or spon-
ge with mild detergent and
water to clean plastic.
Do not use any harsh chemical
products on plastic parts. Be
sure to avoid using cloths or
sponges which have been in
contact with strong or abrasive
cleaning products, solvent orthinner, fuel (gasoline), rust
removers or inhibitors, brake
fluid, antifreeze or electrolyte.
Do not use high-pressure was-
hers or steam-jet cleaners sin-
ce they cause water seepage
and deterioration in the follo-
wing areas: seals (of wheel and
swingarm bearings, fork and
brakes), electric components
(couplers, connectors, instru-
ments, switches and lights),
breather hoses and vents.
For scooters equipped with a
windshield: Do not use strong
cleaners or hard sponges as
they will cause dulling or scrat-
ching. Some cleaning com-
pounds for plastic may leave
scratches on the windshield.
Test the product on a small hid-
den part of the windshield to
make sure that it does not lea-
ve any marks. If the windshield
is scratched, use a quality
plastic polishing compound
after washing.

Storage
Short-term
Always store your scooter in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA10820
CAUTION
Storing the scooter in a poorly
ventilated room or covering it
with a tarp, while it is still wet,
will allow water and humidity to
seep in and cause rust.
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 scooter for seve-
ral months:
1. Follow all the instructions in the
“Care” section of this chapter.2. Drain the carburetor float cham-
ber by loosening the drain bolt;
this will prevent fuel deposits
from building up. Pour the drai-
ned fuel into the fuel tank.
3. Fill up the fuel tank and add fuel
stabilizer (if available) to prevent
the fuel tank from rusting and the
fuel from deteriorating.
4. Perform the following steps to
protect the cylinder, piston rings,
etc. from corrosion.
a. Remove the spark plug cap and
spark plug.
b. Pour a teaspoonful of engine oil
into the spark plug bore.
c. Install the spark plug cap onto
the spark plug, and then place
the spark plug on the cylinder
head so that the electrodes are
grounded. (This will limit sparking
during the next step.)
d. Turn the engine over several
times with the starter. (This will
coat the cylinder wall with oil.)
e. Remove the spark plug cap from
the spark plug, and then install
the spark plug and the spark plug
cap.
EWA10950

WARNING
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turning
the engine over.
5. Lubricate all control cables and
the pivoting points of all levers
and pedals as well as of the
sidestand/centerstand.
6. Check and, if necessary, correct
the tire air pressure, and then lift
the scooter so that both of its
wheels are off the ground. Alter-
natively, turn the wheels a little
every month in order to prevent
the tires from becoming degra-
ded in one spot.
7. Cover the muffler outlet with a
plastic bag to prevent moisture
from entering it.
8. Remove the battery and fully
charge it. Store it in a cool, dry
place and charge it once a
month. Do not store the battery in
an excessively cold or warm pla-
ce [less than 0 °C (30 °F) or more
than 30 °C (90 °F)]. For more
