no. because of wind resistance. More mph means more resistance means more fuel used1978 GS 1000 (since new)

1981 GS 850 (anyone want a project?)

Also engine load. It takes more power to run in the higher gears, in large part due to the wind resistance.Ed
To measure is to know.

AS a side note, altitude, as well, can affect fuel mileage. If you can tolerate the pop-ups and crap ads here's a good explanation.
"A. Fuel economy improves at higher altitude in all engines because the pumping work is reduced. As you go up, a lower manifold vacuum is required to move the car. The lower vacuum means lower pumping work and the result is better fuel economy"
My 850 can range from 30 to nearly 60 MPG depending on altitude as well as other factors mentioned.Roger

Depends on what you mean by “amount of fuel I use”.
Are you measuring the amount of fuel you use in miles per gallon, or in gallons per hour, or in gallons per 1000/rpm, or in ???
Generally speaking, the wider the throttle blades are open, the more fuel goes into the engine.Jim, in Central New York State.
