Guys and gals, Four stroke motors have crankcases that are reservoirs for the lubricating oil. (no oil in fuel for lubrication like a 2 stroke) Hondas and possibly others are finicky about the motor orientation due to the oil possibly draining to 'non-reservoir' areas of the motor i.e. upper valve train, intake and exhaust. The best advice would seem to be to check the motor and documentation for instructions on storage and transportation to keep the UP side UP and vice versa. I know for the guys out there -- it might be time to ...............read the instructions. We all have to at some time or another.
