I admire the enthusiasm and the craftmanship, very impressive, but I wonder about the results.
Blocking the sides of the engine to stop heat from reaching the legs might just push more radiant heat toward the frame and tank. That area, right where the gas tank meets the seat, is already one of the hottest spots on the ST. Wrapping headers can make sense in some cases, but adding insulation or blocking airflow around the engine itself seems counterintuitive. It's not eliminating heat, it's just "blocking" heat arbitrarily, airflow is critical.
I’m genuinely surprised by the amount of time and effort dedicated to the task, but with all my respect, I don't see a solid foundation to support it.
