Hi, Gang.
Picked up my Brand New '11 Fat Bob Friday and just topped off the tank (up to the little black thingy just under the gas cap as per dealer's directions). I clicked around on the display button for the range when the tank is full (it did recalculate) and it is only saying I have a range of 160 miles!!! If the tank is 5 gallons and the bike gets 40-50 MPG, then .....Hmmmm.... let me put on my math hat..... Ok..... shouldn't it read something like r200-250 miles? What gives?

 

Welcome to the innacuracies of a Harley. The guages are never correct. Run a tank through and see what you get on your trip meter...it's the only way to tell. You def won't get 40-50 mpg tho...

 

Do like Widerglider says. I've got to disagree with him on the mpg, though. I've got an '07 Street Bob, stage 1 with Doherty Machine Powerpacc intake, V&H slipons, and TTS tuning and I get about 45 mpg commuting to work, and 50 on long rides, and I don't take it easy on the throttle.

Crazy

 

Forget the gadgets.

Keep a record of your fill-ups and mileage; average them, over time, to get an accurate fuel consumption figure. Use your resettable trip odometer to figure range. Mine averages 45mpg.

 

Mine always says 160 miles at fill-up too. Actual range depends a lot on how I ride. On a steady ride with friends the range is up around 180, on a couple of weeks of short commutes its down around 150.

I just set the trip and fill up at 120 miles.

 

My 08 doesn't have the fuel range thingy but it does have a 5 gal tank and two trip meters.

Even though it has a 5 gal tank I usually only use 3.5 to 4 gals at a time.

The fuel light comes on 160-165 miles into each fill up. I've never put more than 4 gallons in it.
So I figure... 160 miles from 4 gallons of gas = 40 mpg (40 mpg times 5 gals = 200 miles).

On my annual Labor Day week end ride I top off the tank on the way out of town & reset both trip meters A & B. I reset A with each fill up to double check the fuel light (it's never lied). I also stuff each gas receipt in to my pocket.
I leave trip meter B alone till I get back home & fill up again. I add up all the gallons I used & divide it into the total miles ridden.
Over the last three years I've averaged 48.7 miles per gallon on my annual Deal's Gap/Smoky Mnts ride.

 

The remaining indicator is how many miles remaining before you should start thinking about getting gas, I believe. It appears to always leave 1 gallon left in the tank at 0 remaining miles. Thats your reserve.

 

Exactly. Sort of dumb if you ask me... When it says 0 miles left you should be outta gas, not have a gallon left to guess with!
