Everything with the exception of coating the surfaces with oil should work. A battery tender is a must for that length of time. How far from the ocean is the mini storage? Try to stay off of the coast proper to avoid the ocean air. I generally rent a temperature controlled unit for my collector car and bikes during the off season. A breathable cover helps keep the dust off your finish and don't empty the gas tank. Fuel stabilizer works just fine. Add the stabilizer according to instructions, top off the tank and run for 5 minutes to circulate the additive. I've never had a problem with my bikes for a month, or more at a time. Too bad you can't take it with you.
