From Red Plate to Green Plate JR1


New member
Moving my son up in class from red plate to JR1 green plate. QRC intermediate chassis winged kart on 1/8 mile dirt oval. Will this thing want more gear to turn higher rpm? Currently running 11-68 and turning 5,900 rpm.

More air in more power out .
I would run as is , adjust from there .
Maybe even go up to a 12 driver if its fast enough.
