I know I asked this in another thread but re-reading how to adjust the af mixture, I just see how a person just can't seat the screw without having to take the carb off. I knOw I'm getting lazy here but just want good mpg hehehe.
On that one page it says take the carb off the bike then seat it and back out 2 turns. Take it for a run adjust idle, and make adjustments with the af mixture on the bike.
I am Just wanting to understand it better and can't see why the initial adjustments can't be made on the bike.

Ok. DOH. I've been constrict to US GAL as oppose to imperial gallon here in Canada. DOH
So my calculations are as follows
174 km had to switch to reserve at 170
Filled up with 10.91 liters
So now I'm thinking I got 44 mpg.
If this is correc it's not too bad as it is running rich as evident by the carbon fouled plugs.

My buddy :
2007 EFI 1200C
V&H shorts an Fuel pack and SE breather
37 city unless he hammers It then 34
43 Farting around on the back roads
51 mpg on the superslab 75 mph steady
He Is 245 Lbs In gear with a bag on the back, No Fairing.
Me:
2008 EFI 1200R
BOX STOCK,,except for the X14ieD's
37 city unless I hammer It,,then 34
43 farting around on the back roads
49 mpg on the superslab 75 mph steady
I am 230 Lbs In gear with a bag on the back, with a HD quarter fairing
Makes sense,, His breathes better so a tiny bit more mpg at big speed.
Other than that the same....
FYI I got almost the same MPG's before the X14ieD's,
only diff Is that my superslab 75 mph steady was about 47 mpg before
the X14ieD's.

Interesting - and I guess we should be including our body weights/sizes here as they definitely are a factor. Probably my mileage numbers are higher because I'm 140lbs and 5'5".

Topography plays a big role too. Osco lives in a predominately flat state, I live in the more mountainous area of South Carolina and put the most of my miles on in the Western North Carolina mountains. Your hight above sea level has a lot to do with it to.
So the only way you can compare your mileage with anyone else's is to only use the data from someone with the same factors as you......
PS: Disclaimer: I only chose Osco for this explanation because I know he lives in Florida......

What counts the most is your right hand and how you use the power.
A rider who throttles hard from lower RPM's
will get different mpgs from a rider who throttles hard and stays well
inside the power band.
This Is my first Harley, first EFI bike.
My mpg's really sucked when I first got it because I was all into the low
end pulling power.
Once I started revving the bike correctly My mpg's started climbing
big time.
Even when accelerating mellow and to city speeds I get far better
mpg's by reving higher XD

so, are you saying that the fuel economy will be better if you drop the bike down a gear and accelerate, rather than lug it a little in the higher gear?
If that's what you are saying, I think I would agree.
I also seem to get better economy when I am hard on the throttle to accelerate for shorter times, vs. easy on the throttle for a longer period. This surprised me.
