i have a problem with my 125 shifter kart where the steering wheel starts going back and forth like crazy, during left turn exits. i cant figure out the problem i just got the front end aligned and bled the brakes and it still does it...

 

i dunno if you solved this problem, but check the ackkermann settings, also check the steering shaft might be bent, steering shaft could have been drilled wrong, and the steering hub bolts and components make a big deal, also depending on the chasis and front fairing you have the bolt of to the shaft could be different, pics would definately help

 

which kind of shaft are you using ? is there a lot of rubber on the track ?

Which kind of chassis it is ?

Do you have a removable strut bar on the front of the chassis...

give me more detail I raced in F125 ICC 5 years and I have a good experience when it comes to setup a kart.
