I'm sorry that you decided to trade in the bike as the EXUP fault was most certainly fixable. There was no reason why it should have been expensive, either.
I don't know why some valves occasionally bend but I'd guess that cack-handed maintenance is the most likely cause. Usually the amount of distortion is so slight that eyeballing it won't reveal it clearly. A straight edge is required to check the alignment - that, and a certain feel for things mechanical.
I hope whatever you got in exchange is as good as the Fazer.
