Id certainly be checking the cooling system first... I can't see any reason for such heat issues between models unless something was not right....
Firstly, are both cooling fans working ? Do the cooling fans come on at the same temperature as the earlier models ( I don't have the specs, but perhaps some research might dig up something). I know that my bike (2002) doesn't have to get very hot before the fans actuate... Different types of coolant perhaps ?
I doubt whether the fuel mapping would have changed that much between models, it may vary slightly, but wouldn't be enough to make it run that hot...
I've never had any heat issues with my bike at all, thank goodness :)
