I'm getting around 57-64.  I've also started using the lower octane gas (since someone pointed out that the "premium" gas usually sits at the gas stations longer because less people buy it.  After I thought about it, I would bet that the station where I usually fill up my bike probably never sells premium)  My MPG has actually increased since.  I'm keeping a spreadsheet on my cell phone and don't have a ton of data yet, though.  Just a few tanks.  I try to fill up about every 100 miles.

Stock 06.... but getting ready for a muffler change, so I'm curious to see how that will affect it too.

I geuss that and the rejet explains my relatively low mileage. In the 'Burgh there's no such thing as 100% gas. It's all "up to 10% ethanol".

Ok,...and the point of the post is ...???
Yr model ?
Stocker ?
Any mods ?
Type of riding,.......naughty,.. WOT.....nice...50 mph ? in town,..country.....freeways ?

I mean,....you don't get 63 mpg under all conditions. If you average 63, means you're working between 53 & 73 ??? Amazing !!

That sounds right. So you probably didn't have the surging conditions at 1/4 throttle like I do. I need to richen up the "midsection",... when the tank get empty it will be easier to R&R ?.

And it seems to me that if the engine is running lean, (not running right) kinda lopeing along at lower speeds,....that it is getting less mpg than if it was running correctly. So if I richen it up a touch to where it is running smooth, I would expect better mpg, if anything.  

I had no intention of posting here, I guestimate I get about 50 mpg.  Today I had about a 70 mile round trip and a trip planned for first thing in the morning.  I needed gas, so stopped and filled up then filled back up before coming home.  When I got home this had come back to the top.

I drove 58 miles (from gas station to destination back to gas station) and put 1.1 gallon of gas in it.  Works out to about 52.72.

Maybe 10 miles in the city 35-45-50 the rest was on highway and back roads 55 all the way.  I ride like a good boy.

87, dyna muffler, white space mod, did not rejet just adjusted the idle mixture, windshield and 295 pounds of me.

I am pleased!

63 mpg me too

Yeah,.. that paint weighs a ton, don't it?...

96 modle with sportster pipe 1/2 inch hole in divider, memphis shield 18x21 inch, saddlebags, 32,000 miles on it and 48-52 mpg.  
But it sounds so good when its under a load taking off or climing hills. !!
