Here's another interesting link concerning the XR250R oil cooler.

I considered installing this oil cooler, but I think my design has advantages over the XR250R oil cooler. My oil lines are shorter, and less likely to damage other parts of the bike with heat. My oil cooler has a much larger surface area. Also, it is increasingly difficult to find used, XR250R oil coolers for sale. Therefore, my oil cooler installation will undoubtedly cost less than an XR250R, oil cooler installation.
