Whats your gas mileage?

The Busa was 33-35. The Harley just got up to 46.9 according to the tuner. Paper math last tank was 41

Last I checked I averaged around 46 on a highway trip that lasted 4 hours. 80-100 most of the way with a handful of hard pulls.
 
-Digging up this thread's grave-
I used to get 34-42MPG...been riding more often this year and noticed she is thirsty. Started keeping track of mileage and my last 4 fill ups are getting 28MPG :eek: wtf??!
35 of my 37 mile commute is on the interstate at 80MPH...170lb rider, gen1, and stock gearing so 80MPH is near 4.5RPM.
Did the fuel pump mod (drilled & inline filter), new plugs, throttle sync, clean air filter...what the hell happened?
 
As someone else mentioned, I would be concerned about keeping the inside of the motor clean with low gas mileage. The classic experience is a new pipe with tune, too rich at low throttle, carbon fouling and from there things just start going South.

I average between 48-52 mpg depending on the amount of ethanol in the gas, or summer/winter gas.
 
I just did 150 miles on my 2023 Gen III and averaged around 35 mph, I did some interstate, some secondary roads and a few back roads, kept speeds under 80 mpg on the hwy. I still have less than a 1000 miles on the clock so I'm hoping as time goes by and I accumulate some miles mpg will improve. With that said I really didn't buy this bike to be worried about mpg, I bought it to bring a smile to my face when I twist the throttle and the only time I worry about gas is when I start getting toward empty.
 
Mileage with relaxed riding on the Gen3. Quite pleased with this.

Ready to swap out the stock sprocket for a bit more.

That’s where you want to be.

When we talk about “relaxed riding” I am surrounded by quiet country roads lots of wooded areas. To me relaxed riding means including occasional full throttle for short periods. That gives me about the same mileage on a Gen 2.

Anything more than that over here, trying to use the full power of the Busa, two out of ten rides I will either end up in jail, or have a pretty bad crash.

So I am trying to understand how the folks getting mileage in the low 30’s get away with it.

I think you’re missing the point about mpg.
It’s a handy indication of how efficient your engine is running… too lean, too rich or right in the sweet spot, a bit like assessing the way it’s tuned.
I look at my kms per litre ( mpg in your currency ) on my dash each tank full and each ride and I know immediately if it’s running rich or lean for whatever reason.
A bit like having an air/fuel ratio gauge on the dash.
It totally depends on throttle openings and engine load of course, but when it’s a constant cruising speed you just know how it’s efficiency is doing.
