Not to argue with G-man but I've never done anything to "winterize" a motorcycle in all my years of riding. Apart from lubing the chain and putting it on stands. I normally go out and start it every week on two and that's it. I've never had any problems whatsoever with any bike because of this.
I do have one question though...how will water "get into your motor" from starting it? It's a "sealed system" for the most part. I can see the water already in the crankcase condensing but not how you'll add water to your oil. Lastly,I don't "Summerize" my car/truck that barely gets driven for 8 months of the year..... a motorcycle isn't any different than a car as far as I'm concerned.
