The oil cooler is just an accessory and easily removable if 100% originality is desired.
I did note the seat and painted cylinder. He mentions some wear items being replaced, the most obvious being the Kerker rather than the HM340's and that could also include shocks.
Original is probably not a fair thing to say, but I still think clean mostly original is fair. The things that aren't are all pretty easily and cheaply reversible with the exception of the exhaust. And the Kerker is a good looking, high quality replacement and the one on that bike appears to be in almost new condition.
The asking price may be too high, but the posting doesn't come anywhere near the level of the rattle can black backyard bobber/café abominations the ranter is talking about.
