cC
Use only unleaded gasoline. The
use of leaded gasoline will cause
severe damage to internal engine
parts, such as the valves and pis-
ton rings, as well as to the exhaust
system.
INSTRUMENT AND CONTROL FUNCTIONS
3Your Yamaha engine has been
designed to use regular unleaded
gasoline with a research octane num-
ber of 91 or higher. If knocking (or
pinging) occurs, use a gasoline of a
different brand or premium unleaded
fuel. Use of unleaded fuel will extend
spark plug life and reduce mainte-
nance costs.

SCOOTER CARE AND STORAGE

Storage
Storage
Short-term
Always store your scooter in a cool,
dry place and, if necessary, protect it
against dust with a porous cover.
ECA00015
cC

8
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.
8 8
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 sever-
al months:
1. Follow all the instructions in the
“Care” section of this chapter.
2. Drain the carburetor float cham-
bers by loosening the drain bolts;
this will prevent fuel deposits
from building up. Pour the
drained 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 cylinders, piston
rings, etc. from corrosion.a. Remove the spark plug caps
and the spark plugs.
b. Pour a teaspoonful of engine
oil into the spark plug bores.
c. Install the spark plug caps
onto the spark plugs, and then
place the spark plugs on the
cylinder head so that the elec-
trodes 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 walls with
oil.)
e. Remove the spark plug caps
from the spark plugs, and then
install the spark plugs and the
spark plug caps.
EWA00003
w
To prevent damage or injury from
sparking, make sure to ground the
spark plug electrodes while turn-
ing the engine over.
