Since your bike is a 94, you should post your questions in the Evo section to get better and more replies.
That being said, if your bike was a early Evo that had the old style carburetor, I would say use the carburetor for a fishing weight and put virtually anything else in its place. Since your bike is a 94, it has the CV carburetor, which is pretty decent. Take it apart, clean it out, replace all gaskets, rejet as needed, etc. While you are at it, remove the petcock from the fuel tank and have a look at the strainer.

I know S&S was the name for years, but, I've never cared for them. I struggled with a few getting a flat spot off idle.... Took a lot of fiddling with jetting to get right. But, a lotta guys swear by them. I can't say they're terrible, just not my favorite.
I had a Mikuni on my '92 FXR that I liked a lot and an Edelbrock on my Shovelhead that was really smooth.
The cheaper option would be to rebuild your carb. The best option would be to replace it with an HSR42 Mikuni. We have three carbureted Softys in the family, two of which are running Mikuni carbs and the third an S&S which will soon be changed out for a Mikuni. The performance of a flat slide carb is excellent! I recently put a cam in a good friend/customers '96 Heritage, a month later we installed a Mikuni in place of his stock CV carb. He said he felt more of a performance gain from the carb than the cam. I know he was feeling a cumulative gain of both parts, but he talks way more about the carb than the cam for what it is worth...
there's lots of YouTube vids on rebuilding them an making performance tweaks to help wake it up. For about $200 on eBay you can send in your carb Killer carbs will send you back a built up one that's ready to bolt on an will be good if you upgrade your cam.
