I put heat shield on the flat spot of the trunk pan where the fan blows directly on and my seat no longer gets hot "at all". Lots of people seem to put heat shield directly under the seat with good results but the heat would be trapped under the seat where the battery sits. I have a lightning so heat under the tail is a no-go ,all the electronics are their. I also used the same heat shield on the inside of the tank where the rear header is with great results. It use to cook my leg.
