Ran out of fuel, long downhill
Luckily rolled 3/4 of a mile and up to the pump. It only took 3.8** gallons and I'm thinking with the petcock at the rear of the tank, it starved from the looong downhill and didn't actually run empty. I'ved noticed the gauge changes going up and downhill as well. If your trying to stretch a tank and climbing in elevation you could get fooled by the gauge and get caught empty

I can lose a bar on the gas gauge going downhill and regain it on the next uphill. Changing the ride height also has an effect on how far you can go before the first bar disappears.

After running out of fuel a few times, I just try and fill before 120 miles. Usually takes 2.9 - 3.2 gal. Haven't got the ***** to test that shrimpy gas tank on a consistent basis. If you got 3.8, awesome. 
Doesn't the tank shape prevent it from emptying the whole 4.2 gal?

I've put 4.1+ gallons into my tank several times. Without running out of gas, mind you. If everything is good working order you should get every drop from it.
I'm thinking it would need to be one heck of a downhill slope to slosh 0.5 gallons to the front of the tank - like a 50% grade. I'm wondering if you ran out for a different reason?

I ran out last week week at around 105 miles. I was riding with my wife though. Did anyone have an issue with it running rough after putting gas back in? My bike wouldn't idle and seemed as if it was only running on cylinder for a while. When I started to ride, as soon as I hit 2nd gear is cleared up and has been fine since? Is this normal? MAybe the carbs just had to fill back up?

^ If you overfill it, sometimes it creates a vacuum lock (where it can't breath and so the air can't expand, making it hard for the fuel to drain to the carbs). If it happens again, try popping the fuel cap with a spare key or before you ride off and it should fix it. And don't fill it all the way to the brim

996 I am sure there is a Groucho Marx joke about you wife in there somewhere.
I never get that many miles unless I am out on the open road. In the city, way fewer miles, like maybe 80 before I fill up. (with or without my wife)

When I ran out, I only put about 2 gallons back in. That's when it ran rough. Like I said it cleared up in 2nd gear. I was just curious if it was normal for it to do that after running out. Thanks though, I'll keep that in mind when filling up. I tend to top it off to the very top because of its poor gas mileage.
