Do what it says in yer owners manual, duh!!
I would drain most all the gas out of the tank/s, start it up and let it run out of gas. Then drain whats left in the carb. Then, while the oil is still warm, drain the oil and refill with whatever oil yer gonna use in the spring. No need to change the filter. Stick to what it says in the Kaw. engine owners manual.
It ain't rocket science!
