Yes, US gallons.
I am assuming it is set for US gallons vs imperial gallons, correct?

I don't see TB sync fixing this. Well unless you spend all day sitting there at idle! Blah
[MENTION=26122]SandyN[/MENTION] may have nailed it with an unplugged or damaged O2 sensor. Or if someone purposely terminated the ECM O2 pickup with a Simulator plug. The ECM will default to a RICH condition and the MPGs will tank ( haha). If someone were for example trying to squeeeeeeeeeeze some powers from the little fizzer, this would be a way to richen it to the ECMs default fuel map with no O2 compensation.
- This could damage the CAT if ran this way for extended periods. Which even if corrected, could cause poor MPGs.
Do you have digital volt meter and can you confirm O2 sensor is plugged in?
Lift the tank and follow the two leads from the right side of the frame. Mine appears to connect and lay right under the ECM connector:

So an update... I went ahead and changed out the spark plugs with the OEM recommended NGK plugs. I did this the long way, ie.. removing the tank, air-box and battery. Put it all back together and hit the start button and nothing...
I pulled it all back apart to see if something I did putting at all back together might have unplugged something etc. Well as soon as I pulled it all apart, it dawned on me that I might be an idiot, and I was. It was not in neutral when I tried to start it. I put it all back together and put the machine in neutral and hit the start button and she came to life. I took her out for a spin and it literally felt like I upgraded to a larger CC bike in what I felt power wise. I quickly went to some old back roads with some decent twisties and ran her hard. Put a little over 100 miles that day and filled the tank and had 39 mpg. Well that's 6 more than my average, so I am very excited right now. I bet if I tone it down a bit it might even get better. Thanks for reading and providing me with feedback.
