Lets argue carbs
In my experience (very limited) the S&S runs better than the CV hands down.
It out performs the CV in every area except mpg. I does use more gas than the CV.
I will toss the CV and get an S&S on every bike I plan on keeping.
Worth every penny to me.
Just my 2 cents.

But why? What are the specific things you experience with the S&S that you don't with a CV?
Which is to say, for most non-extreme builds, at least on paper, the CV will flow plenty of volume to support the motor. What does the S&S give you that the CV doesn't?

I've got a '91 FXSTC with EV27, Supertrapp 2 into 1, Screamin Eagle ignition and an after market air cleaner. I had Killer Motorcycle build my CV including a hand set screw for the idle mixture and the idle speed. The charge is more than the cost of the Dynojet kit and a set of HD carb gaskets, much less than another carb. It runs and starts great. Passing on the highway I just twist the throttle without downshifting.

CV's can be made to run well with a rebuild performance kit and you can adapt the S&S air cleaner easy , down side is the slides wear and wobble out allowing it to suck air where it shouldn't.
Performance wise the Mikuni is the hot setup ,con's are installation is bit harder and sometimes routing cables and clearances in under the tank can cause bad language, it takes somebody who knows what they are doing to really dial one in right and they run more than the S&S E.
Cool factor ease of installation and the average guy can tweak one in S&S E is a solid choice, while it won't get the gas milage the other 2 will ( difference is minimal ), you don't have to worry about a slide wearing out & dicking with needle setting and e clips.

You are correct....In most cases an S&S is overkill on a stock or near stock motor.
On a big inch/high horsepower motor, an S&S right out of the box is a great carb.
S&S carbs are as simple as a carb gets and that's a good thing too.
Nothing really....
It's a matter of personal preference, like so many other things.
A properly built CV can and will do everything an S&S will do in high horsepower applications, as will an HS42 Mikuni.

Omaha,
The cv can look scary to many people too. My old road glide has cruise control so that is another set of cables going to the carb. The choke is finicky as all hell and it won't stay put easily but that may just be maintenance or a repair. The enrichener on the s&s is dead simple. The customer support from Viola is second to none.
ElguapoRK is ***** deep in a build and I can see where he is going so another $350+ is not a big deal to his install project. Your plans seem to be a little more tame so I think the cv will be more than adequate.
Jasper86 was running a hsr42 for years and he loved it. Maybe he can add some more confusion to the mix.
Good luck,
Tom

Much simpler and easier to deal with.

I need to chat with some Evo-era transmission experts. Something's got me irritated.

I certainly would not spend money on a new carb if you have a good CV. I have had S&S (and do now only because it came with bike) as well as CV. I really don't think what is essentially a old school drag bike carb is an upgrade. If you are not a carb expert and it is not doing a great job upon completion of the project, then just bring it to a good indy for a good carb tune and put the extra $300 into something that really improves the bike somehow.

I have the same carb. Glad I stuck with this one. My bike runs perfect and never skips a beat.
From my experience S & S carbs is they have a real good wide open throttle circuit. It loves to dump gas in your engine. Sometimes it's a real pain when you just want to cruise on the road and your mpg just falls. It's old technology. So not for your average stock engine. Stick with a CV.
