I'm trying to find it... EVO Industries, NOT S&S
The 07 and up (6-speed) bikes have a 1.35 primary ratio (34 tooth compensator/46 tooth clutch) 46/34=1.35. Changing the compensator sprocket to a smaller size, increases RPM, making for stronger acceleration. Changing the compensator to a 30 tooth makes the primary ratio 1.53 (46/30)
Also, if you change the compensator you shouldn't loose your 6 gear indicator light. Changing the front belt pulley you will.
