EBU00427B. STORAGE
Long term storage (60 days or more) of your
machine will require some preventive proce-
dures to guard against deterioration. After thor-
oughly cleaning the machine, prepare for stor-
age as follows:
1. Fill the fuel tank with fresh fuel and add
fuel stabilizer (if available).NOTE:
Use of fuel stabilizer eliminates the need to
drain the fuel system. Consult a Yamaha dealer
if the fuel system is to be drained instead.2. Remove the spark plug, pour about one
tablespoon of SAE 10W30 or 20W40
motor oil in the spark plug hole and rein-
stall the spark plug. Ground the spark plug
wire and turn the engine over several times
to coat the cylinder wall with oil.
3. Lubricate all control cables.

4. Block up the frame to raise all wheels off
the ground.
5. Tie a plastic bag over the exhaust pipe out-
let to prevent moisture from entering.
6. If storing in a humid or salt-air atmosphere,
coat all exposed metal surfaces with a light
film of oil. Do not apply oil to any rubber
parts or the seat cover.
7. Remove the battery and charge it. Store it
in a dry place and recharge it once a
month. Do not store the battery in an
excessively warm or cold place (less than
0°C or more than 30°C).NOTE:
Make any necessary repairs before storing the
machine.

cCBe sure to use motor oils that do not contain

cause clutch and/or starter clutch slippage,
resulting in reduced component life and poor
engine performance.
