I noticed that when I remapped the PCIII that I picked up an extra 10 degrees or so across the board (obviously a leaner map).

Approx. 180 hwy. (in 95 degree heat), 220 in town/stop & go (again, 95 degree heat).

Yes, which unless you're a giant squid, that should be happening slightly more often than "rarely".

Check your coolant, and make sure your fan is coming on around 225. You might need a coolant flush

i didn't mention either of those bc he never said his fan doesn't come on, and i've never seen a cts go out and still read a temperature

man i am in florida and it seems like if i have to wait at a light for more than 30 seconds my fan is kicking on(225+). these things get hot during these summer days. you should be fine as long as your fan is coming on and it is cooling it off. but cruising at about 30-35 my temp is around 215. and no you do not have to wait for your bike to hit 190 to ride. what are you thinking

well i drained and flushed the radiator last saturday and filled with engine ice. It has dropped it down to about 195-201 on hwy but as the above person said, mine too at a light will quickly jump up to temps to make the fan come on.

Did you burp the radiator good?...if you didnt then it might have an air bubble in it because engine ice should have you cooler than that on the hwy...i would say 182-190 is the normal for mine on the hwy...i have a fan switch on mine so i can turn my fan on and run redlight to redlight in traffic and keep it 205 give or take a few degrees as i go and stop.

I've hit 225 on days when i was riding at 30F outside.

the thermostat starts to open around 160. It is fully open around 180 or 185. Fan switch usually kicks on at 225 or so, however that's 225F coolant exiting the engine. The Radiator fan switch activates when temperature inside the radiatior reaches 208 (per shop manual)

Rarely do these bikes get up over 230, however, you're safe to ride them up to 251 indicated.
im running straight engine ice mix and my bike runs hotter then it ever has. i use to stay around 175 while cruisin and higway now i stay at 177 to 190 while doin in the 40. engine ice is garbage. im about to switch when i get some money, i did spend 40 bucks on it . damit
