and i'm at the point where i'm experimenting with the variator. maybe remove 2/4 balls or get the malossi multivar (which is currently out of stock in the usa, it seems).
before i was going to go in and mess with the variator, i was wondering, does anybody have experience with the av10 addon that holds the variator at lower rpm? this thread brings it up

if so, then maybe this addon would be a solution for low speed acceleration...
