I wouldn't worry about it unless you start getting above like 245+
There's nothing wrong with these motors running in and around 200.
On the gen2 stock, fans turn on at 204 and off at 194.
Schnitz flash has the fans turn on at 194 and off at 184
I ride daily in temps well over 100 and fans are pretty
much always running.
The only concern is you do not want to "boil" the coolant.
boiling point of water is 212 add coolant 50/50 and psi to 15psi and you just
raised the boiling point to like 267f
If you start boiling over is the only time to be concerned or
else everything is good to go.
If you want better cooling for your coolant you can try to adjust
mixture rate. If you are running like 50/50 lower to 30% or even less.
Pure water cools better then anti-freeze, but have to balance all
the draw backs. like lower boiling points, higher freezing points, etc.
I do not use any anti freeze in my coolants, no need.
