Fatboy average MPG? Hiway and in town...
 
I know there was a post about this a long time ago, but I can't find it. So let's see if anyone wants to be a part of this. I am quite curious about this. I have a 2002 Fatboy with stage 1 Harley download, i think screamin'eagle a/c and vance and hines sideshot's and get about 40 city or 50 hiway. Does that sound about right? Lemme know. And how can I improve it? If I get a pc3, will my mileage suffer?

If you're getting that you are doing good. As long as not running lean or rich, you are spot on.

Well when I first got it, no popping, but someone said it smelled like gas. (rich I guess) A lot of popping with the V&H exhaust. Could this be rich too or lean? Any ideas?

Hell I've never seen 40 MPG ever. The highest my bike has ever gotten is 38MPG.:D[b]

I was told the V&H always have some pops on decel. Tho they did tell me I am running too rich until I switch out the stock a/c. If your plugs are brown you are too rich. White is too lean

That thing is a gas hog!!!! You should put it on a dyno with a gas analyzer to see why!

I get around 35mpg around town and 40 highway. I know im at the low end of the spectrum but ive had it dyno tuned and the air fuel ratio is perfect through all the gears so im not worried. I really dont care about gas milage anyway.

I get 41-43 mixed riding. If I keep it under 70 I do about 45 or so.

I've never done a whole city tank.
