On our last round trip from SoCal to South Dakota (3700 miles), the norm was 5 bars most of the time. If we pushed the bike hard in 90-105 degrees, or if we rode consistently high RPMs in lower gears, we'd hit 6 bars.
In summary, 5 bars for 'normal' riding, and 6 bars for more extreme temperatures/riding. The only time I saw 7 bars was idling in higher temperatures.
This. Although mine will hit 7 bars eventually regardless of ambient temp, the fan always pulls it back to normal
