If its over 90 F air temp where you are, that doesn't sound too unusual. Hot weather owners always complain about he the the gauge going to 5 bars or even 6 bars (that is the bottom bar 1, marked C all the way through the top bar 6, which is marked H).
According to the Owners Manual, p 35-36, If the all 6 bars are displayed and flashing and there is a HIGH TEMP message in the center of the multifunction meter that alternates with an icon that looks like a thermometer in water, the coolant is too hot. Shut the bike down.
I don't ever see 6 bars on my 08. I run an OEM air filter for the street. I have a PC5 mapped for my mods and I have a very high flow full system exhaust and that does reduce the heat but I would say about 80%-85% of the heat is still there when running. The bike seems to heat up as fast as always but cools down way faster after shut down. It does seem to run a bit cooler than stock but that is more on the highway. Low speed it will climb to 5 bars at a standstill on a hot day.
3 bars (halfway up the scale) has always been normal operating temp since the bike was new. That is where it will stay on the highway in 70-80 degree weather If it is a 90 degree day, highway op temp may be 4 bars most of the time. 5 bars is just in town at a stop light on a 90 degree day. At 20 F air temp, the bike will run a consistent 2 bars on the highway and 2 to 3 bars in town.
