I bought my 04 sporty used. I assumed that it was stock but while cruising this past weekend I stopped at a Harley dealership to look around and one of the mechs asked me after looking my ride over when I intended to finish the conversion. I had assumed that it was totally a xl 883 but he said that it looked like someone had started to convert it . He said that the main reason he asked this was because of the sprocket on the rear was not the correct one that should be on this bike if it was a 883. How do I find out this info? I went to the dealer where I bought the bike but they couldn't offer any clues.
