My '06 has some severe heat issues, and where I live probably has something to do with it. However, I hate giving up easy!
I had removed the inner cowl, tie-wrapped the two halves together, and it did make some difference. The Ivan's FCE made no difference in the heat issue, and I resolved, until recently just to put up with it. A ride with my wife in the mountains changed all that- despite wearing mesh gear, and staying moving as much as possible did not really affect the heat problem, so I decided to take action.
I did the Don Ferrario heat fix (
http://www.donferrario.com/St1300/), and modified it somewhat. He shows running the reflectix up onto the frame on the sides, which I found to be less than optimal. I ran the reflectix UNDER the frame, isolating it from the heat of the radiator. I also added home made "Baker Air Wings", which cost about $12 to build. I took it on a longish ride in both traffic and back road areas, and the heat is reduced at least 80%. Especially while moving, the heat is tolerable. I now have to remember to keep my knees away from the tank, to allow more cooling, but it's not that hard. The tank is much cooler, and the bike is MUCH nicer to ride.
I still avoid riding when it's above 95*, but now at least.morning rides are okay. I'd love to hear of more "heat fixes" if anybody has any.
