Nick, thanks and with respect the +2 degrees advanced timing must not be any reason for higher temperature - the ignition of my Ninjette is advanced by +5 degrees and since that time the temperature for water is lower then before by app. 8 degrees Celsius while the temperature of the oil looks to be the same temperature like before.
Also it's given that my temperature for sure is lower than a Ninja used in a race.
It's important to have a good inside cooling from a rich enough setup in fuel.
Your tipp from before about the Italian water cooler I think is a very good one, it also seems to be lighter than oem and at least in a bike like this I would use an electrical water pump (what brings up to 3-4 hp with the 2-fiddy).
