180-190 is normal operating temps on warm days. My bike fluctuates between 180-200 depending if it's freeway or stopngo streets, but it's also 100+ in Phoenix daily. I would not be worried, but chaging coolant is a good idea. I just changed mine last week. I was told Engine Ice is the best, but couldn't find it anywhere.
