Had the same problem with my R80RT 1986 model .Suggest to drain the gearbox oil ,if it looks like metal flake paint then definitely bearings . In my case it was the output shaft rear bearing , I replaced all the bearings (except the main bearing on the input shaft because to replace this one requires replacing the shaft as well many dollars) my bike had done 275k K/m (170k miles)
