Radiator Boil Over Normal?

Your manual states that idling the engine for more than 5 minutes is not good. Check it out.
My '99WR will boil the radiator if I am riding very hilly, rutted trails that require a lot of clutching. This is to be expected since you are stressing the engine in these kind of conditions.
I know our 4-strokes take a long time to warm up, but it's better to do a short warm up on choke, then putt it around a bit so that there's SOME air moving through the radiator.
You can also try "Water-Wetter" in your radiator. It's an additive that you use with water and just a little bit of anti-freeze. It is supposed to help dissipate heat better than just plain anti-freeze and water alone. I use it in everything I own, but then again I live in Arizona.

The combination of cold air temp and aluminum radiators and motor are definately helpful in dissapating the heat. Your bike is probably fine. Don't freak, have a beer and save the garage cleaning for AFTER you ride. BTW make sure you don't use tap water to refill. You don't want all those minerals in your cooling system. I buy destilled water from the grocery store. That water wetter sounds like good stuff.
