Sta-bil is great, especially with the corn alcohol we're forced to use as fuel these days. Run the engine up to operating temp , then turn off the fuel valve and let her run dry, then drain the little bit that's left from the float bowls. I use fogging oil but my basement storage is rather damp. Then perform an oil change.
Pull the battery and keep it charged.
Wax and spray the metal down with some metal protectant - Silkolene Proprep is my personal fave. It has a very high silicone content so don't use it where any painting occurs, unless you like fish eye!
Treat the drive chain with a good bath of chain lube.
A few strips of duct tape over the airbox intake can help prevent rodent infestations. For some reason they find our air filters to be very tasty! Also, cover the exhaust outlets, it prevents condensation from entering the exhaust.
We had 3 late model Honda VT600's need valves refaced due to pitted valve seats this spring at the shop - best I can figure was the exhaust valve hangs open on the foreward cylinder, condensation creeps up the exhaust pipes and causes rust on the valve seats.
Good luck and get better soon!
