Welcome to the forums. Did you go through any water? I know you said that the radiator(oil cooler) wasn't wet, but maybe it had already dried from the heat when you looked at it. I don't know what else the white smoke could have been except for steam.

I would just check and make sure the oil cooler isn't leaking any oil and then just keep a real close watch on the oil when I rode it. Also, make sure your fan is coming on when it needs to. It isn't water cooled, so steam can't be coming out of the engine. I'm guessing it was still steaming from when you went through the water.

The only time the fan should come on is when it gets pretty warm, like if you're riding it real hard or pulling something.

According to the manual, the fan is supposed to kick on when the oil temperature reaches 270-306 degrees F, so that's pretty warm.
