I love the wisdom here. If you think you’re ever going to dry up any water in your oil or oil lines I don’t think it’s going to happen. There may be more water left in your oil when it’s cold out then when it’s hot I would think, but not enough to seize motors and rust mufflers out . Think about this, water boils at 212* at sea level if I remember high school science which might be a stretch because it was 1970 or so and the weed was pretty good then.The higher in elevation you are the higher the boiling point of water. The more contaminants mixed with water let’s say a tank of oil in a motorcycle it will be even higher. How much I couldn’t tell you without looking it up but a considerable amount of degrees. Did you ever leave a pot of water on the stove boiling? How long did it take to evaporate at what temp? How hot does your motor run? Do you think your motor gets to this temperature stove top temperature no matter the temperature outdoors weather it’s December or August? Common sense should tell you different.
I’ve built 2 hot rod motors in the last 2 years and have had the 1st and 2nd oil changes analyzed and yes water in small amounts were in the oil after 500 and 1000 mile changes. Condensation happens and your not going to stop it especially in a dinosaur vented V-Twin. One exhaust valve is always open and an exhaust pipe is usually within a inch or so away exposing that cylinder to the humidity in air. One or two intake valves behind the air cleaner is another point humidity enters. Not so much in an EFI motor as a carbed motor but none the less humidity gets in.
You want to run your motor in the cold I say go for it. If you let it get to operating temp,that is oil circulating to bring oil in tank to temp that you don’t want to touch it or the heads for that matter that isn’t going to ruin it. I haven’t lost a motor or a set of rusted out pipes in 50 years of riding. Am I lucky?

I love the wisdom here too...

Like the guy who posts a three hundred word answer to a 12 year old thread...

You are wrong. The higher the elevation the lower the boiling point. Not that it's really relevant to a 12 year old thread.
