I just did 240 miles on the VFR (C14 waiting for a K&N air filter from Murph) I needed some green Anti-Freeze to mix with the Water Wetter. Redline recommends minimum 15% for street vehicles, no idea why. I found an Autozone after wandering around for 130 miles. I left at 10:00 am and by 10:30 the gauge said 99. It soon got to 102 and hovered there most of the ride with some 104 and a high of 106. I was wearing under armour shorts under mesh pants. By 2:00 I was standing on the pegs every 3 minutes!
So, its not just a Concours thing. It's mostly a climate change thing and a skin condition thing. I don't expect relief from climate change in my lifetime
The medicine I am on may take 4 months to reach full effect. In the meantime I will keep experimenting and try to make the best of the summer heat.
