Question about 2000 Harley Davidson XL 1200 S Sportster Sport
Is this a recent development? Or has it always left that smell? I had an older Sporty, that I ran too rich for years, it left lots of black soot on the inside of the exhaust tips, and a very pungent exhaust smell on your person. When I went down a couple jet sizes, it got much nicer, and ran a little better as well.

Testimonial: "Thanks for your input. That does make sense to me. However, the service techs have told me that most Harleys are designed to run rich. Thanks again."
As you ride, there is a low pressure zone created behind your back. Exhaust gases from the bike do get trapped in this low pressure zone and this may be causing the problem you're talking about.
Now, the jetting can be correct in your carburator but still the accelerator pump could be a bit on the rich side or if you're "blipping the throttle" too much while riding, this causes that "running rich" smell. If you are concerned about the mixture, put your bike on a dynometer that has an exhaust gas analyser.
