Are you talking aluminum guards that reinforce and support the radiators, or just the plastic louvers that mount in front of the radiators? If it's a full on guard / support then that is a hell of a deal, and well worth the money for the protection. If you are just talking about louvers for air direction, well, you better have a set of those already, or be prepared for overheating issues!
I run the Prestone coolant that supposably works in any vehicle. Never had a problem, even in a 95+ degree harescramble that had me beating the crap out of my bike in lots of 1st gear terrain. It did get hot, but never overheated. I was surprised because the 220's are supposed to be prone to overheating.
