I get 40-50 depending on head or tail winds and how strong they are.

 

my 2011 RGU never got past the 35 mpg mark. and I have 30k on it

 

except for my RC mufflers my 2014 flhxs is stock all my milage is highway and I get 43. m/gal. Usually between 65-75 miles per hour

 

I have a stage 1 and get 37 mpg around town with normal driving. I think this is due to the map the dealer put in because my bike runs very cool compared to some of the threads. I think shes very rich, but im good with it.

 

I have 2 of the 103's. Both stock, except the Dyna has SE slip ons. Both run conventional oil. Both have 7K to 8K miles.

Wide Glide gets 48 to 52.

Road King gets 42 to 44.

This is a 75% mix of rural and city roads, 25% highway.
