Speedo Question
 

I asked this before, but didn't get an answer. I have an '02 HD SuperCrew and I was wondering why it only has 100 mph on the speedo. Every picture I've seen of an '02 has had 130 mph. I noticed some of the non-supercharged HDs have 100 also. I first thought it might be an early '02, but the build number is 5,07x. I've never seen listed as an option or part of a package. Can anyone enlightening me on this situation? I know it shouldn't matter, but it just urks me sometime when I see a picture of one. Thanks.
