Anyone ever have a thermostat problem?

Well, seems like my KFX is running awful hot. It's not TOO surprising since I do have a Wiseco 440 Kit and Hot cams in it. However, it does have me a little concerned.
How do I tell if the coolant is circulating correctly? Take off the cap and look inside????
Has anyone else had a thermostat go bad?
That's the only thing I can think of really.

I know an oversized Radiator and oil tank would be a good investment. I'm working on it.. Which should I buy first?

Thanks

Stock ones have an overheat light on the dash. Have you looked at the red light? Assuming you have one.
