I am helping out a friend with a faulty diff,his diff is beyond repair. I managed to get a diff from Nelspruit. Here is my question  .The diff i removed is a 31/11  ratio and the diff from Nelspruit is a 33/11 ratio.. Is it a no go or what difference would it make.?? My friend is a first time owner on a BMW,so would it work  Another question is ,does anyone know  the spline count on the GSA on the gearbox output and on the diff.This bike has 20 splines on both ends...I also got a shaft fr om Nelspruit with 16 splines on the gearbox end and 20 splines on the diff end...Any help please :thumleft:
