once your bike will nice idle tuned you will be happy about the below 3000rpm range too. Start with basics check TPS zero clean butterflys before and set idle knob fully un-screwd i dont understand that part any advice
when your setting your throttle position sensor make sure your idle knob (on the right between the tank and frame) is wound all the way out then set tps to 0 when setting tps plug in the 2 diag wires underneath the vent panel below the seat on the right (will be a plug that looks like it should be pluged in) remember to unplug when finnished setting tps when wires are pluged in and ignition on it will show DIAG -1 , 0 or +1 fiddle till it says DIAG 0
