At a recent club meeting here in South Australia we had a chap showing us his AJS classic racer. It was my idea of the ultimate of this genre: it did not contain a single AJS part! The only pit was that he had to blow up a very large number of original AJS motors before he realised that what he wanted was something much faster, and more durable, than the real thing.
I try very hard not to destroy any of the things I muck around with. Successful so far.
