If you get your 2024 Yamaha YZ250F and it runs a little dirty/rich down low, have no fear, these maps should help this and help with manipulate the power a little. the Keefer Free Feeling Map 2.0 will get you less engine braking (maybe a little less torque), but pull stronger through mid-top end.
The KK Passive Aggressive Map will give you some added pulling power down low and help mid range while your shifting from second to third gear. This will allow you to short shift sooner and possibly run third gear in corners.
DON’T FORGET TO CHANGE THE TH% under the tab “POSITION”.
We have been running a 13/49 gearing set up but in Millville we went back to a 13/50 to get out of the soft stuff better. We used the KK Passive Aggressive map early in the day when it was deep and changed to the Keefer Free Feeling Map 2.0 in the afternoon once the track was broken in!
