have a 05 wide glide. stock with K and N AF. get 40 mpg no matter if i'm packin or solo freeway. been that way since new.

 

2008 FLHTC (Electra Glide Classic) Low of 42, high of 52. It all depends how fast I go over the passes.

 

Yea, my 2010 Street Glide with the 103" motor is averaging about the 40-45mpg range.

 

depending on wind and speed it gets from 45 to 52 with a 88inch s&s shovel motor.

 

You're doing better than me with the same year and 37 grind cams. I get 35-39. It is carbed though.

 

2003 road king (flhri) average of 50mpg

 

I get 219 miles out of a full tank doing a 70-80 mph, did it the other day going to see family in Wales. usual about 200 ish urban, well impressed with fuel consumption on the 2009 Fat Boy ( Had it since new )

 

2010 Softail - 38 mpg Daily drive to work 70 miles round trip - Interstate running 65-75 mph

 

42-45 on an '04 FLHRSI

 

Don't really know. Don't really care as long as I'm riding it.

I did not base the purchase of my bike or my V10 Ford Excursion for their fuel economy.
