When I ran my sportsman, I used:
Macon: 7.00, sometimes 7.33.
Farmer City: 6.50 - 6.83 (changed depending on track conditions)
and Fairbury would be about the same as Farmer City with a sportsman.
I only ran 7500 rpm tops though, I know some guys that run 7.00's at FC and Fairbury and wind 8000+ rpm.
