COMMON PROBLEMS

Note: below are some suggestions applicable only and exclusively to CORSA RACING KART chassis; remember that not all chassis perform and react the same way and chassis from other brands may require a total different set-up.

Remember tyres are best when new and could play a key-role in getting your correct set-up !!!

PROBLEM	POSSIBLE CAUSE	REMEDY
The kart does not want to turn into the corners	Understeer – too much rear end grip (the balance is out)	• Move front track out • Mount the front torsion bar (in chassis where applicable) • Lift the chassis at the front • Increase caster • Move the seat forward • Mount a softer rear axle • Check toe out (start with 1-2 mm. in dry conditions and 5/10mm in wet conditions)
The kart does not turn out of the corners	Understeer, too much rear end grip (the balance is out)	• Move front track in • Mount the front torsion bar (in chassis where applicable) • Raise chassis at the front • Lower the chassis at the rear • Increase caster • Move the seat forward • Loosen or remove seat supports • Mount a softer rear axle • Check toe out (start with 1-2 mm. in dry conditions and 5/10mm in wet conditions) • Loosen the bar of the rear bumper • Lower tyre pressure
The kart slides at the rear (it turns too much at the front)	Oversteer, too much front end grip (the balance is out)	• Mount a harder type axle • Mount the rear torsion bar • where applicable, remove the front torsion bar • Tighten the rear bumper bolt and bar • Lower the chassis at the front • Increase pressure of rear tyres • Slightly move the seat backwards (you can have the opposite result if yu move it too much) • Decrease caster
The kart slides too much both front and rear	Too little grip	• Mount a harder type axle • Mount the rear torsion bar • Mount the front torsion bar (where applicable) • Tighten the rear bumper bolt and bar • Raise chassis at the front • Increase pressure of all tyres • Raise seat

SUGGESTED SET UP IN RAIN CONDITIONS


- check front toe out
- raise chassis at the front
- increase caster
- move front track out as much as possible
  (with 100cc chassis use front hubs)
- raise seat (in case of heavy rain, 20-30mm.)
- move rear track in
- mount type “N” rear axle
- loosen rear bumper and the rear bumper bar
- loosen the middle axle bearing
- loosen or remove the extra seat supports

Suggestion:
In rain conditions it is usually always better to have little rear end grip (sliding chassis) and a lot of front end grip.
