Burnt Legs

[DaveR]

Whilst out & about enjoying the good weather, i have noticed that my S4R is running so hot that the heat from the engine is making my legs uncomfortably hot. As a long time owner of a '94 900ss I don't recall ever experiencing this before, even when riding through Italian traffic jams in 40 deg heat.
Is this a particular issue with the 'water cooled' Monsters? Under normal circumstances my bike runs at around 78-80 degs, but any hold up will cause this to quickly rise, with the fans cutting in at 104 degs. Once on the move again the temperature quickly falls again, does this point to a problem with the cooling system?
On a recent ride which was blighted by a number of slow moving tractors & other factors, I had to resort to a dual carriageway blast to bring the temperature down.
I have also noticed a hot bum, caused no doubt by the positioning of the rectifier under the seat, where it gets no cooling!
One further question, why does all this warming have no affect in the winter ?
All help gratefully received
