Irradic Fuel Economy!

Postby tilson » Mon Dec 03, 2012 11:22 am



Rode my 89 Goldwing trike to Rockies from Georgia and my fuel mileage veried as much as 9mpg. It actually got better economy in the mountains than on the plains. :?

head/tail wind, rate of climb, humidity, throttle use, weight, tire pressure, gas mixture "E" or not, all affect MPG

Speed effects MPG more than any thing else. When driving in the mountains (slower) my mileage goes up as much as 10 + MPG.

How are your riding habbits, rpms for shifting, peg scraping in the corners, highway speeds, are you filling the tank to the same spot on the filler neck each time? And as said the fuel itself as stations will put as much ethanol in to gouge the customer as they can get away with to make higher profits. It all plays into effect in fuel mileage on our bikes.
these fairings were designed in the late 70s and early 80s technology era while we had 65 MPH speed limits on the highways and that is where you will get your best highway fuel mileage and yes wind plays in the factors with load. If you set the cruise control at 65 MPH your RPMS should be @2500 RPM at which you can get upwards of 45-48 MPG.

I just can't drive 65! :oops:

?? Those numbers confuse me a little from my experience...??
On my GL1500 Aspencade of 1996 with 120,000 miles on it ....
At 3000 RPM's my bike is cruising at 67-68 MPH and delivering a consistent 42 MPG
I can bump that up to 3250 RPM's and cruise at more like 72-73 MPH and get 37 MPG.
In order to get 45+ MPG I need to slow down to 55 to 60 MPH at which point I am near that 2500 RPM mark....

Tall Tulsa vented windshield, no wind wings, solo rider, reasonably calm day (no significant winds), ambient temps around 80.
Darkside car tire rear 175-75 and double dark front BattlAx BT45. I am about 300 lbs at 6' tall.

Load, Wind, Drag, state of tune, terrain, tire choice and inflation pressure, are a few of the variables in MPG.

I track mine every tank full..I watch for dramatic changes in averages over a few tanks to indicate a potential problem.

I agree with this statement and my bike is in 2750rpm range at 73 mph and stiill gets 45 riding 2 up. My new rear tire is a 195/75/16 car tire and should have bike between 2400-2500 rpm at 75mph cruising. Last 1300 mile trip overall milage averaged 49 and hope new tire will break 50.
