Looking for opinions...I have a ‘16 k 1600 gtl. As you know there’s a bar graph on dash for water temp. Every since it was new it ran, depending on weather at 2 to 4 bars, average 3 bars. It would have to idle quite a while before it would get warm enough to kick the fan on. I just recently had the 18k service done which included removing the radiator & flushing the cooling system. Now the bike runs at 5 bars & will go from dead cold to 5 bars within a mile. It will also climb to the point to kick the fan on every time I stop at a couple stoplights. I went back to dealer, they said there was an air bubble in system & it was fine now. Bike still runs at same temps. I just recently completed a 2000 mi trip with no overheating problems, but I can’t help to feel like there something restricting the flow, not letting the coolant circulate properly. Has anyone else experienced anything similar?
