Has anyone experimented installing a close-able vent on each side of the 'Maintenence Cover' to deflect & harness the hot air from the backside of the radiator? This might serve a dual purpose; (1) reducing the inflow of cold air sucked into the feet/leg area & (2) provide warm/hot air to keep feet & legs warm. A simple circular vent with corresponding cover could be closed when not needed. Even with boots & thermal socks my 78yr-old feet & ankles get uncomfortably cold. My 400 riding buddy suffers the same problem & is contemplating installing deflectors on the fairing - but I'm not convinced deflectors would help much?
