FYI:
I started tracking and recording my CB1100E gasoline mileage starting near the end of my 600 mile break-in period. I used trip computer A for tank to tank mileage, and trip computer B for accumulating miles. I also compared the trip computer calculated mileage compared to my calculations. What I found is the trip computer tank to tank mileage can vary due to many reasons. But it is still a decent indicator.
I was more interested over a long term/accumulative mileage using trip computer B. Over 890 miles, my trip computer B displayed 52.2 mpg. Actual computed mileage was slightly better at 53.3 mpg. A small difference (Trip B being lower mpg vs calculated) was consistent throughout. I plan on doing another sample next year after my CB has over 2,000 miles on it.
If your head is spinning and you are asking yourself, "What's up with this guy?" My only defense is I am retired Civil Engineer who had a long career analyzing dams. This is what nerds enjoy doing...
Not spinning at all...fully understood and appreciated.
I also tend to analyze to the nth degree.
Was a power station operator for Los Angeles Dept of Water and Power from 1970 to 1979, mostly at Sylmar Converter Station.
Operated an electric motor rewind shop 1979-1983.
Worked as an industrial electrician for a while.
Managed a tire store.
Got into automation in 1985, primary sales and business management
Managed US sales for Hirose Electric (#2 Japanese connector company) for a year, between automation jobs (custom automation is a risky business).
Retired in Feb, at age 70. Company closed its doors in May.
In my limited (2 days) experience:
1. Speedo is extremely accurate (2018 Yamaha XT250 would top out at an indicated 84 MPH, but true was about 76)
2. Consumed gallons is extremely accurate
3. MPG is very, very close
Most of today's riding was 2500 to 3000 RPM, with some short bursts to 4,000 and one to 5,000.

But most of the Spring Mountains (Mt Charleston is 12K feet) roads are either ascending or descending. Lee canyon climbs from less than 3K feet to over 8K feet in 14 miles...so, not much hope of better economy when leaner, if EFI does not fully compensate.
In 2013, on my 2012 865cc Triumph Bonneville, on the Extraterrestrial highway, on a long clear straightaway, wind dead calm, I decided to check for max speed. At 112 MPH, a sudden gust blew me from center of westbound lane to center of east bound lane. Glad it came from north, instead of south, as that would have put me into a very rocky down slopping shoulder. Never did find out the max!
