I took my 2009 K1200LT in for the 600 mile service yesterday. It overheated 3 times on the 15 mile ride there (Stop and go I-5 traffic) about 83 degrees out. I was going about 5 miles per hour in the left lane when it forst happened, I got over into the right lane near the Tacoma Dome and got some clean air, I felt a rush of hot air on my legs and the bike started to cool down. I got off I-5 and tried to take some side roads and nurse it to the dealership, I hit more stop and go traffic and had to pull off the road and shut the bike down in some shade. At first the dealership thought that the bike had not been properly prepped (none or not enough coolant, I bought it from a different dealership) but they called me today and said the radiator fan was not working. I've ridden six hundred miles but this is the first stop and go traffic so this could have been inop since I got the bike. Is this a common issue? Could I have damaged my bike having it overheat? What should I look for? Thanks.
