I have seen mine get up to 220F on very hot days (very rare here) while sitting in traffic. Drops back down to 200F when moving. the only time I got worried about burning it up was stuck on Lazzele Ave in Sturgis (08) and it got up to 240F. I was roasting too. Didn't hurt the bike a bit, I recovered with a cold beer.  Interesting to note that before the BB the engine ran consistantly 20 F cooler across the board.
