Chris is right that it is not acceptable for a bike to this and dangerous if that sprays on a leg or rear tire. The caps we have all changed to raise the operating pressure a little, increasing the boiling point, not for gasket leaks or other issues. Doing that, changing to the ICE coolant(the factory fluid I agree, looks overly strong/undiluted) but I think the biggest help was modifying the fan shroud..removing it to be exact. I have tracked my bike now at 4 events in July Texas heat and no coolant issues. Admittedly, I only have 1300 miles on her.
