It’s that time of year again, so I thought I would post the storage procedures that are contained in the 1978 BMW Owner’s Manual for those of you that don’t have access to such. The following is a reproduction of the storage procedures specified by BMW on page 35 of the 1978 BMW Owner’s Manual:

If you intend to lay up your motorcycle during the cold season of the year or for a long period, the following precautions will help to guard against corrosion and superficial damage:
Drain the oil when the engine is warmed up, clean the oil mesh strainer and oil sump.
Add corrosion inhibiting oil up to the lower mark on dipstick (app. 1 Liter = 1.05 US quarts). Run the engine for about 1 minute off-load. Remove the oil filter and close the empty filter chamber. When storing for more than 6 months, drain oil from gear-box, swing arm and final drive and add corrosion inhibiting oil. Contents: gearbox 0.4 liter (0.4 US quart), swing arm 0.05 liter (0.05 US quart). Place the machine on its center stand, engage 2nd gear and turn the engine at a fast idle for a few seconds.
