Remove the spark plug wire and ground
it. Operate the electric starter to turn the
engine over several times and coat the
cylinder walls with oil.
3. Lubricate all control cables.
4. Put the frame on stands or blocks to raise
all wheels off the ground.
5. Tie a plastic bag over the exhaust pipe
outlet to prevent moisture from entering.
6. If storing in a humid or salt-air atmo- sphere, coat all exposed metal surfaces
with a light film of oil. Do not apply oil to
any rubber parts or the seat covers.
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 ex-
cessively warm or cold place [less than 0
°C (30 °F) or more than 30 °C (90 °F)].
