Um- some of the guys trying to help you are not up on earlier models.
so, if the plastic backing plate is gone, and the pleats of the filter are exposed to the air, and you have free-er flowing mufflers then you have a "stage 1"
good for 7 to 10 HP usually, depending on components chosen.
You can generally tell if your carb has been modded if the plug over the idle mixture adjust has been removed ( which requires, pulling the carb and drilling the plug out).
a bone stock carb will often "sneeze" ( backfire through the air cleaner) as the motors revs past about 1800 rpm when leaving a light.
If that isn't happening, then your carb is probably tuned pretty well to compensate for the increased air flow.
MPH on a well- tuned carb will be about 42 or better at 65 MPH

Carbs were offered on HD's up to 2006. 06 was the last year you could get a carb. FI on a 2001 is Magnetti Marelli (MM) which is harder to tune than the 02 and later Delphi injection. It takes an experienced tuner that knows what he is doing to work with the MM's. Because of that, a lot of folks that had the 99-01 MM's would often switch them over to carbs.

I didn't know carbs were available as late as 06. As Gomer would say "Shazamm"

You do want to make sure your carb is jetted to compensate for the increased air flow. In the old days we could just look at the spark plugs for a light tan color on the electrode which meant "normal" mix. A white ash color meant lean and if not rectified, over time could burn you valve seats. We actually used to pop the float bowl unscrew our brass jet and drill it out with the next larger size bit that would not go thru the OEM hole. Then we would run it awhile and check the plugs. Sometimes we had to drill it out again.
With ECM's it's a bit harder to read plugs with any accuracy. The carburated models didn't have an ECM but rather an Ignition Module. I'm not real up on how much they monitor the A/F mixture, but you need to make sure you are not running too lean. I would give heed to Dawg's info on getting it tuned if the engine doesn't seem to running right or it's running real hot.
