To me I don't really care what sort of internals you have got inside your forks, motor or whatever. The first and most important thing with a build for me is if it looks externally correct/period and meets the rules if used for competition if those are requirements/desires. Is the finish correct, is the colour correct? I will admit I am pretty pedantic with that stuff. I go to great lengths to research correct colours, finishes and decals. I do not expect others, especially ones building bikes specifically for chasing trophies or on a budget to have the same outlook. Those details do not matter to some. Some are just concerned with meeting the bare min requirements of the rules. That is fine. That’s not to say i will only use NOS decals with 1970’s adhesive on them but I will go to great lengths and do a lot of research to find out if what I want to use or correctly reproduce or claim reproduced as an exact reproduction will look correct and be correct. I am quite obsessed with attention to details . For me I like the vintage and period bikes that I like because of what they look like. Unless I was racing and desperately wanted another (there becomes a point where they are a pain in the arse to store/display and are dust collectors) plastic trophy then I would fit emulators and use the best modern shocks and modifications I could afford that met the rules, after I was sure my riding ability and fitness was the best it could be as well. I actually have got a set of emulators for some 36mm KYB forks sitting doing nothing, new in packet and I would actually rather spend double the price on reproducing period correct internal parts or modifications than fit them. But like I said I am totally obsessed with being as period correct as realistically possible. I would much rather fit a vintage ‘fork kit’ or use restored period correct shocks or engine internals (eg not modern V-force reed blocks) that were available when the bike was current, even if the rules allowed me to fit more modern stuff.
