I just traveled from Louisiana to Arkansas. I installed the refer you sent me and it worked GREAT. The temperature in Arkansas was around 105 degrees. The bike rally had a parade while I was there. My ’09 road king did not overheat once. It ran around 230 degrees.There were other ’09 bikes there and they were shutting of their bike to keep them cool. I asked some riders if I could get the temperature of their oil and it varied from around 270-280. No problem with the Ultra Cool Refer. I recommend this cooler to everyone that shut their bikes off, so you should be getting some calls. Not only is this a great cooler the service I received from your support staff was incredible. They took there time and answered every question I had with a smile. I can’t say enough about this cooler other than it is worth every penny and GREAT.
