Unfortunately everyone has a different idea on what 'some' is
My point Loz was that although a thing is irrelevent or just plain wrong to modern eyes, at the time those parts were the result of somebody looking to find a new way of doing something and shouldn't be dismissed or sent to the scrap as you alluded to simply because they don't conform to our current way of thinking. All of those things you mention were good attempts at something different and shouldn't be dismissed simply because the idea failed.

some to me is something that can't be seen....ignition, porting, engine internals, fork internals, that sort of thing..
Maybes are shocks, pipes and other parts, as long as they look period. I've been guilty myself in the past with fat pipes on my DT1, fluro pink plastic, and modern rims on old bikes but the older I get, the more I think we need to limit modern development on old bikes. If we don't enforce it we'll end up like classic road racing where some disgraceful stuff has passed muster for so long that a lot of period integrity is lost.
