Yes, that's the problem when you come too late into the game. I wish I had started this 10 years ago, but back then I lived on the 'dark side', only dealt with DOHC 750's from 81 and 82. I finally saw the light and came back to the original bike. Now I have to start collecting, but it is pricier than it was 10 years ago that's for certain. Although, I cannot imagine how anyone ever restored a bike without the internet. Just not enough salvage shops around locally to do all the scrounging needed for all the bits that would need to be replaced. My hat is off to the 'older' restorers (and by that I mean years spent restoring, not physical age).
On a side note, if anyone ever comes across a copy of Cafe Racers by Mike Clay (published 1988), I would love to get my hands on it.
