I'd leave it on the assembly lube until you come to actually want/need to start it. Seal off the various openings to prevent corrosion, fit a set of spark plugs in to prevent the cylinders/pistons rusting, fit an oil pressure switch again to prevent corrosion and apply grease or oil to any surfaces you don't want to rust such as the flywheel - it can be cleaned off before you fit the clutch with a suitable degreaser and likewise removed from any other surfaces you don't want grease on but it's a lot easier to remove grease than it is to remove rust pits from the flywheel surface for example.

When you do come to start it, remove those plugs and dribble some oil into the bores, let it soak in for a while with the plugs refitted then remove them, put rags over the holes and spin it on the starter to eject the oil. This will help "wet" the rings to help them make a good seal so when you come to start it, you have a better chance of it firing fairly easily.
