When the motorcycle is to be stored for any length of time, such as during the winter season, it should be prepared for storage as follows:
  Clean the entire vehicle thoroughly.
  Empty the gasoline from the fuel tank, and empty the carburetor float bowls. (If left in for long time, the gasoline will sour.)
  Remove the empty fuel tank, pour about 1/2 pint of motor oil into the tank, roll the tank around to coat the inner surfaces thoroughly, and pour out the excess oil.
  Remove the spark plugs and put several drops of SAE 30 oil into each cylinder. Kick the engine over slowly a few times to coat the cylinder walls with oil, and replace the plugs.
  Set the motorcycle on a box or stand so that both wheels are raised off the ground. (If this cannot be done, put boards under the front and rear wheels to keep dampness away from the tire rubber.)
Spray oil on all unpainted surfaces to prevent rusting.  Avoid getting oil on rubber parts or the brakes.
Lubricate the drive chain and all cables.
  Remove the battery, and store it where it will not be exposed to direct sunlight, moisture, or freezing temperatures. During storage it should be given a slow charge (one ampere or less) about once a month.
  Tie a plastic bag over the exhaust pipe to prevent moisture from entering.
  Put a cover over the motorcycle to keep dust and dirt from collecting on it.
To put the motorcycle back into use after storage:
  Check the electrolyte levelin the battery, charge the battery if necessary, and install it in the motorcycle. Be careful that the battery vent hose is not pinched and that it is routed away from the chain.
  Bring tire pressure up to normal  Front tire   1.7 kg/cm2 (24psi)
Rear tire    2.2 kg/cm2 (31 psi)
  Make sure the spark plugs are tight.
  Check the engine oil.
  Fill the fuel tank with fuel.
  Run the engine for about five minutes to warm the oil, and drain the transmission oil.
  Put in fresh transmission oil.
  Check all the points listed under Daily Safety Checks.
  Lubricate the chain and the other points listed in the Lubrication Section.
