Here are my two '84 Stumpjumper Sports:
The above Sj was modernized with an 8 speed cassette, and cerca '93 Shimano XT & XTR components except the calipers which, I think, are stock, and hubs which are LX. Unfortunately someone shortened the bull moose handlebars by about an inch on each side. Works great & handles any off-road trails I want with the 2.25" WTB Trail Boss tires.
This second SJ Sport was hidden in a Craigslist post for $75. I believe it was stock when I got it. I replaced the Mountech RD when the upper pulley seized on me. I'm really happy with the XC Triple pulley RD I swapped in and the Suntour friction thumbies are excellent. This one also goes anywhere I want off-road, but also does really well on paved surfaces with the 2.1" Maxxis DTHs.
Edit: the cables are long on purpose: I'm contemplating different bars.
