I would put Sta-bil in the tank and run it for a quik ride or two to circulate it through the carb, works really well when your bike has to sit unused for extended periods of time, unless you wanted to drain your tank and pull your carb off and clean and blow it out with air pressure to ensure there is no fuel left anywhere inside. I have always used a light coat of synthetic axle grease on the flush mount section of the air filter. Other than that I cant really think of anything else I would do, we don't get any snow here in NC so I usually ride all year round.
