My 2011 F650GS is kicking the radiator fan on if I ride in city traffic for more than 4 blocks or after my 30 minute 70mph commute while I park it. If I idle at a stoplight for about two minutes I get the yellow engine engine warning light and my temperature gague flashing. Ambient temperature is about 75 degrees Fahrenheit. My coolant is full but darker in color I don't know what color it was to start. The bike runs at an appropriate temperature if it is kept above 30mph. I have cleaned the radiator already. I recently got back from a rally where I rode two up (heavy loading offroad). I had no overheating problems at the rally but did have trouble on the way home. I punched the oil pan on the ride so I am heasitant to try to waranty the bike only to find I have to pay for engine surgery. This bike also has gear shift indication problems in 5th gear but that has been happening since I bought the bike. Any off the hip suggestions? Is this another problem with this model or am I fucked?
