yes, tecnically you can run A class in a non sanctioned race. but if you go back to an AMA race and you get protested then you have to go through a long process of paperwork and getting all your results together and calling the track to prove that is was a non sanctoned event. and say youve done half a season racing B in 2012, then someone protests you and you go through the paperwork proving your a B rider. you still get all your previous results and points taken away. so say your trying for lorettas and youve done 3 qualifiers and youve already qualified for 2 regions.. then you get protested.. then you will have to redo all your area qualifiers. i know $1500 is hard to pass up and ive thought about taking that same chance, but its not worth it
