I totally agree that fitting a sheepskin seat cover will fix the issue. It seals the gap between the tank and the seat, which stops hot air from under the fairings escaping through that gap. In addition, I'd never put anything critical in the pie warmers as the heat in there can get extreme. I made some measurements and found that on a 30 degree day, temps in the Pie Warmer reached 43 degrees while on the move, and 57 degrees soon after the bike stopped. Who knows what temps would be reached on a hot day! I used my pie warmers for tools, spare ear plugs, chamois etc, but NEVER for wallet, phone, camera etc.
