OK guys on my cr500 ported for 100 and I run 105... I am telling you I watched my Temps up the trail I am between 130 and 150... 40 to 50 degrees today.... climbing through trees steep spring like snow is when I am getting into the 190's ... I run engine ice.... I wonder why mine is staying cooler on the trail... I start at about 6000 and climb to 10000... I am going to try the q7 and see what happens....
