Assuming you do not plan to start the bike during storage, I recommend draining the tank, removing it, pouring in about a qt of cheap engine oil, move the tank around to coat the inside good, and pour out the excess oil. While the fuel lines are disconnected, drain the carbs, and run some WD-40 through them. This will remove any gas that still might be in there, and coat the inside of the carbs with WD-40.
The reason for this is to prevent damage from ethanol gas. It used to be that all you had to worry about was the carbs getting all plugged up with what was left when the gas evaporated. I thought that was bad. But since the advent of ethanol in gas, I have seen carbs literally destroyed by it. Aluminum and brass corroded, steel rusted, and metal and plastic melted. It will also cause the tank to rust, and do the same thing to the petcock as it does to carbs.
I just had my carbs off, and found corrosion and melted rubber. And my bike has never sat for very long.
I am a motorcyclist, NOT a biker.
