Well I guess that's one method of figuring your mpg. How about just zeroing your trip meter when you fill up and then dividing the amount you have to put in the tank at the next refill into the miles you have riden?

07 Low Rider, stock 96" with VH Big Shots, Fuelpak and some sort of high flow air filter. Around town I get about 40 mpg and on the highway 50 mpg. Probably could get some more if I was a little easier on the throttle. I also zero the B trip odometer with every fill up because i don"t trust the gauge. I divide the gallons of fuel into the miles riden.

Just ran through a full tank. put on 170 miles, pretty much all to and from work which is alot of start and stop (and occasional heavy throttle, of course!). Guage is on the empty line. Figure there at a 4.6 gal tank comes out to 37 mpg. Probably could go a bit more... so I'm figuring 37-40mpg city driving. '05 fxdli.

I haven't read every single post as this is a long thread, but of what I did read I seen no mention of speedometer error. Accurate mileage calculations will only happen when your speedometer is reading correctly. Calibrate your speedo to a GPS and then figure your fuel mileage.

Step 1
Fill up your tank at a gas station and write down the mileage that the odometer says before you leave. An example would be your odometer says 31,000 miles. Make sure to fill the tank, not just get some gas. Place the paper in a safe place where you will know where it is when you need it next.

Step 2
Drive the vehicle until you need to put more gas in it. It doesn't have to be empty, but you will want to put some mileage on it to get a good average.

Step 3
Fill the tank up again and write down how many gallons it took to fill it up. Let's say you need 10 gallons of gas to completely fill the tank.

Step 4
Write down the new mileage on your paper. Subtract the first mileage (from Step1) from the new mileage and write down the answer. Your new mileage is 31, 200. Take the new mileage reading of 31,200 and subtract the first mileage reading of 31,000. You are left with 200 miles.

Step 5
Divide the number of miles you drove by the number of gallons of gas it took to fill the tank. The answer will be your miles per gallon. Divide the 200 miles you drove by the 10 gallons of gas you used; 200 divided by 10 equals 20. You are getting 20 miles to the gallon in our example.
"57MPG vs. 20MPG." that's the difference between a carbureted bike that not jetting right vs. an EPA lean fuel injection. It's not so much the increase in fuel purchased, it's all about "fuel range." (Especially in central Calif & Northern/Central Nevada.) Not unusual to see "No Services next 140 mi." At least on the roads I take...

Who ressurected an old thread? I feel like a newb for responding and not checking.
Yes, I edited my post...*chuckles
