Last Winter, I put a plastic vapor barrier under the car and used a breathable car cover mostly to keep the car clean. I have made it a practice to stuff an oily rag into the exhaust pipe(s) of my cars and bikes and the same with the carb intake. This is mostly to keep critters from finding a home. Their are also elaborate plastic bag containers, some with frames, which use chemical drying agents to keep condensation from forming during storage. I used to do this with my BSA until I got sick of the process of rolling it in and sealing it up (I almost dropped the bike while inside.....not pretty). Liberal doses of wax on painted or finished surfaces is a good idea, perhaps even a coating of WD 40 on less well finished surfaces, but be careful what you spray it on!
Depending on how long it will be in storage will probably determine how fussy you want to be, but once it is put away, leave it along. If it is possible, bring your battery inside and place it on a wooden board, maintain the electrolyte level and buy a battery tender....a very good investment.
Good luck. Spring is just around the corner. Ha!
