IOk so on my bike it shoots out coolant when I'm pinning it until about 20 minutes of riding it will stop shooting out. When I'm done riding I open the top and coolant is still 90 percent full but if I let it cool for about 10 minutes and ride it the exact same way it does the exact same thing shoot out for 20 minutes then stop. I recently put in a billet water pump as well. Ny bike is not over heating which is a plus.
