I've had two 1st Gen. B12's now.
It seems to me that these bikes are very sensitive to air-filter cleanliness.
I discovered this a number of years ago while riding my red bandito to New Mexico from New York. As I went farther and farther West, the bike started running increasingly rich.
I DID check the air filter. It looked clean enough and certainly viable, (to my somewhat experieced eye).
I even took the carbs apart in BLAZING-hot, Kansas rest area and bumped the needles, (leaner), and it was ...slightly better. Couldn't figure it out... the filter showed no signs of being clogged.
Finally, I pulled into Santa Fe during a terrble lighting/rain storm, where i pushed the bike mercilessly for hours. In the morning, the bike started up with a huge belch of black smoke, and ran like dogmeat. The "mechanic" at the local Soozook shop talked vaguely about "a valve job". I tried running the bike without an airfilter just for laughs... wouldn't even start.
Distraught, I plugged onward to Colorado Springs, where I changed my tires and found new air filter at a great, friendly Suzuki dealer. I was getting desperate, and finally, north of Denver, installed it.
BOOM! night and DAY!! the f**ker SCREAMED northwards. After that, the trip through S. Dakota (including Sturgis, One Week After the Fact).. and over the top of the Great Lakes through Canada and home. A total blast. Good ol' Bandit.
The thing was, the new filter wasn't THAT much different in color than the old one. Deceptive.
Just the other day I RINSED my current paper filter (yes, with water...no scrubbing though) and carefully blew it dry. (I'm too poor right now to buy a new one at $37).
Suddenly, the bike LAUNCHES through the upper midrange.
Clean yer FILTER, boys.

I wonder if your bike also had some altitude sickness and/or some bad fuel. Santa Fe is 7000ft, Colorado Springs is 6000+ft and Denver is 5280. As you go North on I25 you drop in elevation. If I remember right, the needle helps in the mid-range. Jetting for sea level and a dirty filter I can see you having problems. I have a 1st gen 1200 as well that I bought used. It's seems to be jetted perfectly for out here. I've riding it to the top of Mt Evan 14000+ feet with no problems.

Mt Evans, eh? Rode my trusty GS1000E up that while touring with the Grateful Dead in 1981.
Both of my bikes were jetted precisely for about sea-level + 300 feet, using Ivan needles, Yosh exhaust, and modified (holes-drilled) airbox.
I've been on various long-distance trips (with both bikes, totalling about 60,000 miles)... as long as I have the filter clean, she'll go anywhere like a.... well a BANDIT.
