I would think that if a fellow were to carefully build an advanced component entirely from verifiable period materials, using only verifiable period tools and equipment,
Just where are you going to find all these "verifiable period materials" ?
And just how do you enforce that "verifiable period tools" ??
(And just what real purpose does imposing this limit on technological advances do anyway ?)
If there is one thing that is terribly apparent about modern motorcycles and their manufacture,
it is that modern metals are soooo much better than decades ago,
and modern machining and production methods have come a looooong way over the past few decades.....
Cast steels used to be quite a rare and expensive commodity not that far back in time,
and now you can buy electric furnaces to almost do this in your home garage.
Aluminium alloys used to be prone to bubbles in pouring and cracking in service,
and modern alloys are way way way better than they used to be.
Why go back into the stone age ??
If these 4 valve manxs were not around in the 'classic era',
why allow them into classic era racing.
They should be in the relevant age bracket.
And if they are not then competitive, thats why they didn't develop back then either.
But, perhaps there should be an experimental class of racing ?
