COMMON PROBLEMS

Note: below are some suggestions applicable only and exclusively to Haase 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.
