If you had to, how far could you ride in one stint?

You ought to send that one to Martha.  She might send you a plate of brownies for the testimonial.   

Maybe laced with pain killing herb!

Well, that was implied.

I couldn't do that on a Jackal... Not with the stock seat!!! [emoji33]

   I have an Airhawk with an extra inch of padding.  Still, lots of nsaids would be needed.

In October 2008 I rode my 1200 Sport to Barber for the Vintage festival.  I tried to ride the entire distance back to Bellows Falls, VT(1,200 miles) in one shot.  The temp when I rolled through Knoxville was 40 degrees and a steady ran was falling.  By Roanoke it was in the 30's and the rain switched back and forth to snow.  I was soaked through and miserable.  I didn't have heated gear.  It was 10 or 11pm by the time I hit PA and salt/sand trucks were on the interstate.  Eventually a State Trooper pulled me over and told me to get off the road somewhere near Lancaster.  I only ended up doing about 830 miles but 600+ of it was in sub 40 temps in the rain, on a bike with no wind protection.  I was so tired that when I pulled in front of the hotel I forgot to take my feet off the pegs and almost dumped the bike at a standstill.  That was the single most miserable day of my motorcycling life.

On my V-Strom, which had handguards an Airhawk and the largest Cee Bailey shield, I did many 600 mile days in complete comfort.  That's with no interstate riding at all.  It's amazing what a little weather protection and heated gear will do. 

I rode 600 miles in a day on my California Touring last Fall.  It wasn't fun.  The windshield creates a lot of buffeting above 60.  It's like getting your helmet slapped back and forth all day.  With the right windshield I could probably do 800 miles before I felt like I had to get off the bike.  I think the cruise control adds at least a hundred miles to my mileage potential because I've got mild carpal tunnel in my right hand.  A 1,000 mile day with the bike set up right would be possible but I wouldn't enjoy it.

I just checked the mileage, and it looks like I rode ~2k miles in 2 days back when I bought my Cal 2 auto from a guy in Columbus, OH, fly-n-ride back to Phoenix. I only took interstate from Columbus to St. Louis, 2-lane rest of the way from there. No WAY could I do that now, I don't even know how I did it then on that beautiful but oh-so-miserable Cal 2 seat and those awful swoopy bars (changed those out quick).

  That was the single most miserable day of my motorcycling life.

Been there, done that. I was coming back from Boston to St. Louis after Thanksgiving one year and the rain turned to snow in Columbus, OH. I was scared _itless riding on the highway, in addition to being frozen solid and stiff. I was dreamily thinking about how warm those people in their cars were, looking at me like I was an idiot (I was).

Ditto on the windshield, can't abide a windshield that causes head-buffeting.

People laugh but that's why I drilled a 1000 holes in the Guzzi barn door windshield. Blocks 90 % of the wind and eliminates almost all buffeting. I can run 75 mph wearing a baseball cap and sipping a pepsi.

1 hour

HA!  That's about right. 
 
Although this post asked how far could you do today if you had to, I have enjoyed reading about other WG member's truly epic past exploits. 

I'm too new to riding to be able to answer beyond "until its time to stop", and I haven't had the opportunity to reach that point yet.  I've daydreamed of doing an Iron Butt 1000 between Phoenix, and my hometown in northern Cali's wine country (830-ish + filler miles), but it'll never happen.
