    2014 ultra limited, Andrews 26 cams, Rinehart true duals, screaming eagle intake, pcv with auto tune, all trim tables look good across the table but at zero throttle at 1000 rpms it requires large increases in fuel to bring afrs into spec, meaning less than 14 to 1 afr. Has MoCo leaned out idle to pass emissions specs on these bikes.
