For over 20 years I have done the same winterizing procedure with all my bikes and never had any problems: install new oil and filter; fill up the tank and add StaBil to the gas; trickle charge it once a week for a couple of hours; fill up the tires and let it sit on a piece of old carpet with plywood underneath and cover it. Come spring, change the oil and filter again, check everything and I'm ready to go.
