The extent to which you have to go and how much attention over the months you have to pay to the engine is probably dependent on the humidity level the engine will be exposed to. in an unheated, enclosed garage I think I would turn over the engine by hand at least once a month, along with (before turning it over, actually) removing the spark plugs and spraying each cylinder with oil fogging spray available at boat shops. Be ABSOLUTELY SURE THERE IS PLENTY OF ANTI-SIEZE COMPOUND ON THE SPARK PLUG THREADS!!!

I think duct tape over the exhaust outlet, and intake horn(s) would be a good idea, but it wouldn't reduce my monthly routine ... just give some barrier to the moisture entry ... but, there still will be some condensation inside, regardless!
