I am considering the purchase of a new 2008 910R. I live in Las Vegas and it is not unusal for the temperature to be over 100 degrees in the summer. My game plan in the summer is to ride the bike early in the morning when the sun comes up before the temperature reaches 90 degrees. I have been told tht the 910R runs hotter than the 910S. Can anyone confirm this and tell me why. I really like the looks of the 910R. I also heard by word of mouth that someone iwith a 910R changed the cooling fan from a three to a four bladed fan and this helped lower the temmperature. I just want to make sure I do not purhcase a bike that will have overheating problems that will affect the engine life and performance. Any feedback would be greatly appreciated.
