Honda cb400 super four User Manual

Extended storage, such as for winter,
requires that you take certain steps to
reduce the effects of deterioration from
non-use of the motorcycle. In addition,
necessary repairs should be made BEFORE
storing the motorcycle; otherwise, these
repairs may be forgotten by the time the
motorcycle is removed from storage.
Change the engine oil and filter.
Make sure the cooling system is filled
with a 50/50 % antifreeze solution.
Empty the fuel tank into an approved
petrol container using a commercially
available hand siphon or an equivalent
method. Spray the inside of the tank with
an aerosol rust-inhibiting oil.
Reinstall the fuel fill cap on the tank.
If storage will last more than one month,
carburetor draining is very important, to
assure proper performance after storage.
