I am currently getting about 26 on a 2009 FXDF after installing Rush 2.0 slip-ons, PCIII and SE AC. I need to tweak the map a bit to try and boost that number up.

 

I ride my bike a lot on the back country roads and I figure I get in the mid to low
40's.
I think it all depends on how heavy you are on that right grip :-)
I don't care if I got 20 mpg. Man, I love riding that bike!!!!

 

I drive in stop and go traffic all the time,so I'm at 35s

 

Around town 36-38mpg. Highway, 43-45mpg. Have 2007 FXDC. You need to run your bike to at least 210-215 miles on the trip odometer to see how far it'll go. Carry a little gas with you in one of those tiny red plastic gas cans you can get at Pep Boys. My low fuel light comes on when I have 2 gallons left in my 5 gal. tank.

 

I got 46 mpg before the Stage 1 and 42 mpg now. Mixed riding and cruise around at 3000 rpm.

 

34-40 in all around riding, on my '01 fxdp, carb., Stage 1 with screamin eagle slip ons. usually its on the lower side.

 

I do a lot of highway riding and im getting around 45-48 mpg

 

i have no idea... everytime i say i will take it easy to see what it gets i end up pounding on it... sad i have had the bike 2 years and have NO IDEA!

 

around 50mpg highway (switch into 6th at 60 mph) and about 33 in the city.

 

Fistfull riding gets me 35
daily driving (50-50) avg is 40
long hwy trips I've gotten 53
