Default Possible fuel problem

Bought a used "09" XL1200L with only approx. 5500 miles. Bike is in excellent condition, etc. However, I have noticed that when I get down to about 1/2 a tank of fuel, it seems to not run right. Almost like it's running out of gas and you need to switch to your reserve. If I'm not mistaken, there is no "switch" to turn on a reserve, just a warning light "low on fuel". Is this right? Just wondering if it's me or something I can check...
My first tank, I mistakenly ran regular, yesterday - switched to Sunoco premium. Hope it's just the gas, and not something else. Other than that - seems to run fine as long as I don't run in too high a gear. (Lugging). Still getting used to it. Last three bikes were metric. A big difference!

You might have a hole in the pump hose inside the tank. With a full tank the hole is submerged, as the level drops the hole can start drawing air.

Very possible, CHarley. Also, on an '09 with only 5500 miles, it could have sat for some time. Could be bad gas like he is guessing.

Diagnosis: Refill with good gas and ride a bit. See if anything changes.

Default New update

More info, might not be a fuel problem. Took the bike to a HD dealer because it finally threw an engine code. Says it has a bad IAC...
I'm still not convinced that is the problem. Had a very experienced mechanic give an opinion without riding it, he says it's starving for air, causing it to not run just right. I put some turnout pipes on, but this problem was happening before pipes. Trying to keep her pretty stock, don't have a big budget to just try and see what works. Any suggestion? Could a air filter cause that?

Charley idea makes the most sense, either that or the tanks vent is blocked.
(vacuum in tank)
When it acts up take the gas cap off and put it back on.

I would check your tank filter also, and vacuum lines for leaks

I also like to give it a taste of the racing gas (106) in the spring to help clean out the old crap
