How do you know when these bikes overheat?

...when it's too late?

Sorry for the newb question, but theres no temp gauge on this thing!

also, has anyone modded a fan on these since theyre not water cooled?

I let a friend ride mine at the Little Sturgis rally over the weekend and they over heated it. She would start but would not run hardly at all. When they overheat you WILL know it. They get DAMN hot and if they will start they will not rev at all.
