[size=1em]I'm surprised your ECU is still working if it's getting that hot.[/size]
[size=1em]Have you checked the voltage across the battery when the bikes running?[/size]
It should be 15 volt. If it's a lot more maybe the voltage is not being regulated properly.
[size=1em]Or may be excess current is not going to earth. [/size]
And you've got excess current going through the ECU to get to earth.
Check the earthing of the regulator/rectifier and the connections to it (finned bit close to the head stock under the tank)
[size=1em]I caveat all the above with (I'm not that good on electrics).[/size]
