That... is odd. I feel almost nothing coming from those vents, especially if I'm moving at all, even when I'm just waring jeans. Do you wear boots? Where do you feel this heat?
To answer the OP: I have the Cee Bailey's sport screen in dark smoke. I went across the desert last Saturday from Phoenix to Laguna Hills, CA in 119*F and it permitted plenty of airflow to my vented jacket with the screen in the lowest position.
I wear jeans and boots 100% of my time riding. The warmer air coming from the radiator seems to updraft to my lower body which was the same on the Gold Wings and Concours 14. Its not hot, just warmer than the surrounding air around me which makes things a little less comfortable above 90 degrees. On the other hand, the TTSE is much more pleasant to ride in cool/cold weather than my K1600.
