2014 kx250f rpm idle throttle response

Recommended Posts

2014 kx250f. cant seem to get a believable answer. searched quite a bit to no avail. if u know a thread please direct me to it. have an hrs/tach. I set idle at 1000rpm. when I just barely roll throttle (1/32-1/16), the motor revs up to about 2000-2500rpm. I am unable to use 1000-2000rpms. it seems to take off like it has a power band right from the start. throttle cable seams correct with about a 16th of play. adjusted high/low idle knob, didn't fix. inspected throttle body, didn't notice anything. checked for vacuum leaks, didn't find any. just seems to overreact at minimal part open throttle. makes trail unbareable and track is jumpy and squirlly. still somewhat of a beginner rider. thx.

the idle should be set to around 2000 rpms.  1000 is way way to low. I'm surprised it will even run that low. Maybe your hour meter is calibrated right.
