I installed a 10.5"x24"x.125" piece of semi flexible rubber behind the radiator and it extends out to just in front of the cylinder heads. The hot from the radiator is then forced out the side louvers and is blocked from going back on and through the engine. Reduced the heat alot. I also made side wind deflectors which push the hot air out farther not allowing it to hit the driver. The plastic was a front bumper from my local auto body shop free. Prior to this I bought a neoprene wet suit $6 cut it into a large section and installed it over the air filter housing and frame under the tank that stop the tank from getting so hot.
