I'm struggling on this

plus as usuall gregz drunk as a pig but have nice chit

Well you buy to sell. But there is still some meat on the bones at ten.

Sorry can't help you on the z900 valuation - but I also have an unstamped engine for an 81 GPz550. Not seen one before and very unusual to be registered without any markings in uK.

Anyone else got an unstamped engine? pretty rare I guess.

Oh, your buying Billy Turners stuff?

Yeah, I think it's quite safe to say that if it's minty mint then it's easily worth that. No two ways about it.
