One Hot Motor

I saw a bike in the grocery store parking lot today. It looked different, so I went to check it out. Small displacement vertical twin cruiser. From the styling, I'm guessing a Yammie, but I wouldn't say so under oath.
A few years old, but not exactly "classic" age - maybe five to ten years old, but all the logos and insignia lost to time, use and rust. I respect that.

I also respect modifying a bike to make it yours. Cosmetically. Structurally. Even modifying the engine is cool, if you know what you're doing.

But here's the problem.

There were two hoses leading down from the neck area of the frame, and they were capped off, with the metal pieces welded to the frame. There's only one reason I can think of for hoses like this to be routed up from the motor area to the neck region, then back down in front of the downtubes. A radiator. Now, there are good reasons to modify many parts of an engine, but I can't think of a single reason that makes it a good idea to remove a radiator from a motor designed to run with it, then use that motor in Central Texas in the summer.

WTF?
