When its time, I change the oil, switch back to antifreeze (would flush and refill I didnt have water in it), throw her up on stands, take my wheels and tires inside (I have slicks), take the battery out and put it inside on a tender, don't touch it til spring because road salt gets everywhere if you decide to ride "on a nice day in dec-feb". I also brim the fuel tank completely full so theres no chance of rust.
I used to do stabil but it's not like my bike is going to sit for more than a few months. Havent had an issue in the past handful of years not putting stabil in the tank.
If you do decided to start the bike when its fucking cold outside, let it get up to full operating temp or you run the risk of building condensation inside the motor.
