The fans in these things like to run almost constantly, I would say that's far from normal. They are also notorious for blowing the fan fuse all the time. Take the hood off, and you'll see two little orange fuse holders, mounted on posts. The fan fuse is the one on the right (I think). It'll have a red 10 amp mini fuse in it, along with a spare (Kawi was thinkin' on that one). Check 'em both, but make sure neither is blown. The other 10 amp fuse is for the fuel pump I believe.

If you were going easy on the engine and riding fast (MPH), it won't come on. If you were riding slow or really getting on the gas, it will get hot and come on.
