I have a 2012 RTL which I bought used. When I bought it the previous owner had blocked off the upper outlet for the radiator on right side of bike. This keeps some of the heat off of your right leg an foot but I still get some heat from the lower outlet. My question is, can I block off the lower opening also without causing over heating problem? With both openings blocked looks like to me that the heat can exit out the bottom, right or wrong?
