Update - As this thread stated, I installed vented lowers on my SESG. Last Friday morning, I left to head to Daytona bike week. It was 36 degrees and pouring rain on the way down. I rode for 5 to 6 hours in the rain with the temp rising from 36 to 46. I have to say the lowers made a huge difference. On Saturday and Sunday it got close to 80 and with the vents open there was no problem. On the way home, I started out with the vents open since it was going to be warm. Once on the interstate, I tested riding with the vents open and closed. I really couldn't tell much difference in temp but closing the vents at highway speeds really decreased the wind turbulence.
So far, I plan to leave the lowers on all the time. Adding them made a huge difference when it was cold and raining plus highway speeds were more pleasant.
Thanks to all for the input. This was well worth doing.
