I just have the stock CV on my 90 but it is a really good performing carb. I get 43mpg and the power is great with a 2:1 exhaust and a hypercharger air filter.
One thing to consider, if you ride a lot to different altitudes I think the S&S is easier to change jets out. Just a thought.

The '88 Sportster version did not have an accelerator pump, so avoid that one for a big twin.
Carb
Intake manifold w/flanges
New o-rings and carb grommet for the manifold
Throttle cables (for post '89 model of your bike)
Air filter backing plate or assembly for '90 - '98 (they actually hold the carb on the engine)
Enricher cable/elbow/valve (if it's missing from a used one)
Throttle cable bracket (they are sometimes missing from a used one also)
You may need to make a simple bracket to relocate the enricher cable because it comes off the rear of the carb as opposed to the front on the original carb. Also, if it has the plastic elbow for the fuel line inlet, replace it with the solid brass version. You can pick one up at the dealer and I don't have the part # but they are cheap - maybe 5.00
One more thing - most of the backing plates or brackets are made for the post '92 models with breather type heads. Not a problem, just use the original bolts with heavy 5/16" washers or spacers to bolt the plate/bracket to the head.

Reason: one more thing
I just read all your other good info in another post about CV carbs.
Honestly it all makes me think I might just get an S&S Super E for my 85 FXWG.
I'm very familiar with the Super G on my chopper.
Any great reason to pick the CV over the Super E?

Actually, No.
Only experience I have at all with an S&S was on a '72 Shovel that belonged to a guy I used to (try to) ride with. I called it an S&S "floodmaster."
But seriously, if you're familiar with them and have hands-on experience, you may be better served to go that way.
I have a bone stock, all original motor in my 85 FXWG. I'm thinking of replacing the stock Kehin butterfly carb with an S&S Super E. Will I see any perfomance gains over the stock carb that is in good shape and tuned?
The stock Kehin was a total POS. I still have one in my junk carb box. The Super E will be much better. You'll have to get some jets because the jets it will come with, even if you order it specificall for your bike, will be pig rich.
