Welcome to H-D Forum!!!
Enjoy the new bike, and welcome to the forum. And you are correct, there is a lot of good information here, and a lot of good people here giving out sound advice (normally, LOL) Becareful, though, this site has been known to become very addictive (just ask my wife, LOL)
Now, figure out how to post up some pics, and you will be all set. Here is a post to help you out https://www.hdforums.com/m_834925/tm.htm

Ironhorselady: "S" stands for "Sport". I would find another parts guy to deal with if he didn't know that. The 'Sport' was made for a few years and discontinued in favor of the "Roadster". Your Sport came with upgraded forks that have more adjustments than normal and better springs. Some people look for a used set of 'Sport' forks to put on their newer Sportster. I am not sure, but the heads may have been worked over a little too. Someone on this forum will know. ........... BC
RaftGyde was sweating over my bike for me (once again) and I came home with a clutch cable 4" too short. Luckily, the shop's only 5 miles down the road. . .

The thing that really got to me was the first cable, the wrong one that was 5" too short was $72 before my discount. The second one, the longer one was $30. They looked exactly the same except for the additional 5" in length. So how the hell could the price be so much different? Oh well. At least we ended up with the cheaper one.
