180 isn't bad. A Duc with sound hoses and clamps should hold its fluids to 230 or more. But ....

First check your thermostat. I should open at around 160. Hang onto the cooling hose between the thermostat and the radiator while checking your temp gauge. Or, to be sure your thermostat is opening fully you can remove it and check it in your kitchen in a pot of hot water with a candy thermometer (best when your wife isn't at home).

My St4s runs hot also. 190s and 200s (in traffic and climbing a long steep inclines in slow traffic) and I live in one of the coldest places in the lower 48. Last year I bought one of these after reading a favorable review in the 1/10 issue of MCN. After you get access to the radiator cap it will drain and refill your system in seconds. No kidding. My bike still runs hotter than I would like but I know there is no air in the system. I always felt like a putz burping hoses.
