Isn't the AFR goal to be constant 13.1 ?  Anyway, mine is still stock -- 5,100 miles averaging 37 2-up @ 75 mph, higher when I'm alone or not going as fast.

Not really, your stock bike will change both spark and fuel depending on load/rpm.
Sounds like your MPG is in the ball park at 75, 2-up, you will probably get mid 40's alone, slower from what we see here. A lot depends on the riding style, local conditions.

Same setup and get 35-39 MPG.  Only 1000 miles on bike so I'm hoping it will improve.

Getting mine tuned in 2 wks. to see if it helps.

Jerry, I have the exact same setup as you including the map and just got 32 MPG on my last fill up?  I've never gotten 40 MPG even at a contant 60 MPH.   Taking to a TTS Tuner next week.

Yikes! So far this change has done all I could ask for. Steve's stock map performs fine on my bike. I would consider having a dyno performed just to see if I could tweak in a few more mpg...but I don't know anybody in this area who has the expertise.

By the way, my mileage is based on my commuting back and forth to work on the Beltway averaging around 65 mph. On trips where I'm traveling slower...with a group...I average 41-42 mpg.

We'll see what the tune does for me.

I have a 2008 CVO Ultra Trike Conversion and with Rinehart True Duals, SE Heavy Breather, Power Commander. No heat problems and I get average of 38MPG two up pushing two 225/15 tires through a differential.  Not too bad I would say for the load.

we have just been on a 1.500 m trip with our "sister", same bike except red paint and 100% stock engine. Fuelled up exactly the same amount each stop under various conditions (Autobahn, backroads, mountain passes). I was quite impressed as my slightly modified bike has until now seen no dyno, just SEPST smarttune. I would have expected the engine with some 25 % more output (higher compression, AC, pipes, cat-free ond so on, evidently running stronger)  to consume significantly more fuel ...

Should I start worrying ...

[CVOfan]

I'm running the HD Pro Super Tuner, Rinehart slip-ons, and SE Heavy Breather...bike has around 800 miles...getting 43.3 mpg
