It was shipped with a 295 / 70 and now that I've road tested it I understand why so many kept on me to upgrade. Performed really, really well right out of the box.
Only have put 30 miles on it but what a boost to performance and finally running the way I thought it should!
What's up with the loud intake vacuum noise on this setup? Reminded me of when we used to flip the air filter cover on the chevy 350s. Guess a bit louder pipes might drown out that different sound ... lol

Modern fuel injection is so much better from every perspective, economy, performance, and easy tuning, but it sure doesn't sound as good when you floor it. lol

I get that intake moan with the AN "big sucker" air cleaner combined with a vintage style 7" round cover. Probably not a lot of room between the cover and the filter, so air velocity going in is pretty high. I suspect the original 8" cover might be a bit more efficient, but I like the looks of this setup, so it stays.
As long as everyone is comparing mileage, I'll throw my numbers in. Back when I ran the Keihin CV (#45 pilot/#185 main), I averaged 50 MPG on the highway, day in and day out, maybe 45-46 in town. My best one tank average was 57 MPG (downhill, with a tailwind).
In '02, the shop talked me into a Mikuni HSR42. With the stock jetting, I got around 38-44 MPG. The Mikuni is also much more variable than the Keihin, and very sensitive to how much right hand I use.
In '08, I installed the "mileage kit" in the Mikuni (#20 pilot jet-down from #25, #50 accelerator pump jet-down from #80, #98 needle and #165 main). My otherwise stock motor seems crisper and "happier" jetted a bit leaner, and mileage now varies between 42-48 MPG. Of course, this is on E10, which is all you can buy here.

WHAT??? You got to be kidding right? S&S is the easiest carb tuning that don't need electronic, Economy and performance try 48+ Mpg that runs like a rocket.
You need a computer just to tune injection. Let me know what happens when a sensor goes out

Unlike the old days when I had to swap jets at the track from reading plugs and be careful not to leak fuel all over and catch car on fire!
My SnS on my 1995 RK ran great, but only returned 36.17 mpg average while I owned it...I think it was my driving style as I liked to hear the pipes rap so I was not driving for economy (I daily drive a Prius now and have gone 600+ miles on 10 gallons so I do know how to drive for economy and I don't do it on my Harleys).
But to your point, I was mad when I put on straight pipes on my Springer and I and to buy a $253.99 Fuelmoto power commander to get the bike to run properly. Unlike my Vette where I am constantly tuning for best track performance, the Springer has no closed loop system nor even o2 sensors so I wish it could have just swapped a jet and gone on my way. I'm not racing it so I don't care about squeezing another tenth out of it.
And I did have my TPS sensor go out on my Springer, and since I couldn't get the codes from its rudimentary computer, I replaced the idle air controller mistakenly trying to get it to idle properly. Lifetime mileage on the Springer is 36.93, not much different from the SnS on my RK.
So in summary, I agree with you, I would have preferred a carb on my bike. But I would never go back to a carb on a vehicle I race.
If I get back into muscle cars (sold my 71 442 convertible and my 72 Hurst/Olds a couple of years ago), I will definitely go with Quadrajet equipped 454-455's as nothing beats that sound.

41 on the first tank full with lots of excited acceleration runs just to feel the power. I have some easier miles planned this week and will report back. I always look at mileage with each tank full.
But! The real interest is to have the motor run right, cool, clean and efficient in the sense of smooth operations. I believe when you have a bad carburetor your stressing the motor. With every sputter and hesitation she had before I worried it was putting bad loads on the entire system.
I was just reading about ABS issues and the high cost of repairs for the system, and I'm fully aware of the complex, and costly operating systems on the newer rides. I'm just thankful to have the upgraded carb and crane ignition system running it's best.
I would like to DINO the bike to get all the settings perfect in place, but that's another huge cost for my wallet. I'm extremely happy taking a more moderate approach because it's running so well right now.

41 not to bad pushing a dresser with a heavy throttle hand, specially if 2 up. Yost power tube proly get ya 45 Mpg. under the same conditions, Fine tune makes it better.
My build is Ev27, HD lifters, adj pushrods, roller rockers, built & shaved heads, 10-1+ Cr weiscos, Dyna 2k igniter, S&S E with yost. Gets me 48 Mpg in the fast lane. Just Sayin.

Nice build! If that's your ride in your post it's looks to be all of about 400 pounds. I doubt I have much more than 70 Hp and 900 pounds of steel and another 300 for me and my wife. That gives you the advantage on MPG.
Speaking of the weight factor ... I tell my wife that I'm balancing about 1,200 pounds when we come to a stop, or during slow speed maneuvers.

Told ya that you needed to ditch that POS carb for an S&S or a Mikuni. Glad it's working out for you.
Joe, I put EFI on Dr.Linda's Sporty. I built the computer myself, loosely based on a Megasquirt 1. Total control of every map, closed loop, narrow band (wide band is supported but more money and more amps.) She says it's "like riding with an automatic transmission. Just put it in gear and go." And EFI can have plenty of intake roar. I had quad throttle bodies on my Rolla with a similar EFI setup. That one was 1.6L and about 160 HP, NA.

Sometimes you just have to dig deep and spend money in the right direction.
