I believe it was MY 1994 and after that they began having issues with the stress cracks near the steering head. The swingarm issues affected these years too it's good to ask the seller.
Your right about the mufflers, I guess it's just a personal choice but that's an easy swap. And I'm not a fan of the Carb upgrade, Keihn flatslides are good for the track but they don't have a choke and are a PITA trying to start the bike when it's cold out.

There's also one problem that I find quite often is the front subframe that holds the instrument cluster and headlight, they were not welded very well and would easily crack during a tip-over. This bike looks to be in great shape so I wouldn't worry too much about that problem.
Keep me posted Noah.
