The compensator runs on the outside of the front gear of your primary. There is a large flat internal spring that sometimes breaks or wears to the point of rattling.

It's possible it's just loose...have you checked to make sure?
If it is loose, take entire primary chain assy out and inspect charging rotor. If compensator is left loose for a long enough period of time, the charging rotor can move back and forth on the splines of the crank....this can cause the splines to wear out on the rotor.

After researching and watching (listening to motors idle) on a few youtube videos, I think it is a loose Compensator Nut and/or worn Compensator; as you do...
(note: I have additional noise, from the left side primary case, like a bad bearing sound "rattleing" at 800 to 950 rpm, goes away at 1000 rpm -- that has been slowly steadily getting worse; along with the chirp on decelleration).
I will try the Compensator Nut first and let you know how that turns out this weekend.
Update Saturday 4-6-2013:
**ENGINE IDLE RATTLEING WAS FIXED:
found loose Compensator Nut; removed it with about 10 ft lbs. of torque!!!!, caught it before major damage... Removed, cleaned, retightened nut with High Heat Red Loctite to 150 ft lbs. **
Thanks to "Dakotabos" and "Woodbutcher" to send me down the right path.
This video also convinced me of the potential fix since my "idle" rattleing noise was not quite as bad as this Harley; [which I believe also had a loose compensator nut] (see youtube link).
