I have a 2009 kfx450r. Having a tough time finding an AFR that are right for my mods. Mods are..98mm C/P high compression piston, +2mm crank, fuel customs intake, Accel jeep coil, full fmf titanium mega bomb exhaust, power commander V, auto tune. Where i ride is mostly 500 feet above sea level. Any help would be much appreciated. Thanks

12.5-12.8 is a good safe spot to aim for.

that fmf exhaust is holding you but up top too. Probably gain 2-3hp switching to monster or dasa
