Yes , it's water cooled

I use Motul coolant ... There are many brands to choose from

You mix the shit with water and pour it in.

When you look in the "hole" and the coolants almost pouring out, keep it a little below that. It has to fill the radiator all the way

Hmm, I would use distilled water and something like water wetter, or engine ice. I mean, only time i DONT have something like that in my bike is if its sitting out in a garage all winter.

OP, dont forget to leave the drain plug out when or if you drain it, and just dump water (from a gallon jug or whatever) into the radiator and let it just run out, always seems to flush out a lil extra. And when you refill it with whatever coolant or water combo you choose, that you fill it up to the neck of the filler, then tilt the bike to about 45* with the cap off. Obviously tilt it down to the left since filler is on the right rad. You will notice air bubbles and the level will drop a little once uprighted again, re-fill, tilt again, do this til no more air bubbles/coolant drop is taking place.

As stated above, Red Line Water Wetter, or Engine Ice drops temps a few degrees.

using straight coolant does not mean it is going to cool better. straight water will actually cool better than straight coolant believe it or not. your best bet is to use water wetter or engine ice IMO.

how often do you have to fill it up?

Yea 100% coolant will not make it run cooler.  However that is what I run in all my bikes except the Hayabusa street bike.  It never boils over and does not seem to run too hot.  Don't think your bike is running too hot unless it is boiling over.
