Is it poss.ible to change this, and how does it affect the handling. myson races this in India in Jr rotax

It is possible to change the geometry on the font end by using either a half degree pill or full degree pill. The R31 comes standard with one half degree pill on top and a central pill on the bottom. By rotating the pill, you can achieve desired camber/castor. Leaning the spindle kingpin back (more angled) increases castor. Tipping the kingpin away from the kart increases camber. Tipping it inward will give you negative camber. Castor in/positive camber=More grip Castor out/negative camber=Less grip
