hi all......i need gearing recomendations for the following.............


bk2 with a 13 double checkpoint motor

mf2 with a 19 turn money checkpoint motor

xxxcr with a Co27 stock motor

bj4we with a 10 double checkpoint motor


all are going to be run on a 45 x 120 red clay, blue groove track.



so far on the cr.....i'm thinking the stock spur (78) and a 20 or 21 pinion......and on the bj, the stock spur and a 16 pinion.

the rest, i'm not so sure about and need the gearing help. thanks in advance for the help.

You're good on the gearing for the CR. I run 20-78 on my CR using a Banzai prepped CO27. Ran it at Cactus on their big track. Still felt like it had some legs to stretch
