Those are almost exactly the same numbers I have with my 12 RK. 49.2 has been the max, so far.

2011 RKC 103 and Dynoed.
1 up City - 33. Mixed - 36. Highway - 41(70mph +)
2 up the numbers really don't change much.
I don't shift till 3000, and don't go into 6th gear till about 65mph.
Bike runs great.

Cannot really accurately compare later injected bikes with earlier carbed models in most cases. The Screamin Eagle insert came with the Screamin Eagle air cleaner kit, which was the filter and backing plate. A carburetor modification is something different and USUALLY was a Thunderslide kit, but not always. Sometimes nothing was done, other times jets were replaced or even drilled out. To tell if it has a Thunderslide kit, remove the air filter and look down the carb throat. If the slide is black plastic, then it has the Thunderslide kit. Those kits were pretty adjustable, including the metering rod length. If the plugs are pretty black it may be running too rich, also look at the muffler outlets if they are sooty black.
When I installed a Thunderslide kit in a 1200 Sportster I had years ago, the directions I followed as far as the jets and settings turned out too lean and I had to richen it a bit by lowering the metering rod clip a slot or 2. I would bet, if you do have the Thunderslide kit, the rod might need to be raised a slot and see how that works out. Raising the clip to a higher slot allows the rod to sink farther in the jet and leans it some. If I am remembering the directions right.
