I have/had Buells ranging from 4000-80,000 miles and some were pretty trashed, I have removed them before but so far my lucks held out and I've never had to replace a bad one? Sorry, I don't have an old one to send, maybe someone else does I hope? I would check BadWeb if you come up empty here, they got some riders on there!
I know the trick to an easy mount swap is to have the front tire supported by a chock or stand and evenly support the front of the engine as well. You can loosen the big bolt a little first to adjust as necessary. EZ PZ after that.
