the white pinion gear may work fine but it is not meant for use with the bit char-g, the white gear are to be used on bit racer. using the black gear should solve your problem….hope that helps.
SpeedKing is talkin’ about an american thing known as the K.I.T. Racing (Kinetic Interactive Technology) by hot wheels. I saw it at Walmart and saw the motor that “closely resemble” a Bit Char-g motor. I then bought the thing to find out if the motor could be used on my bit char-g (it came with 2.6 micro b), but found out that it is incompatible. The only thing i found is that the heat sink and tires can be used on the bit char-g.
