  In the same spirit as heterotic weight lifting, B-L lifting is a way of
replacing the superfluous and ubiquitous U(1)_{B-L} with something else with
the same modular properties, but different conformal weights and ground state
dimensions. This method works in principle for all variants of (2,2)
constructions, such as orbifolds, Calabi-Yau manifolds, free bosons and
fermions and Gepner models, since it only modifies the universal SO(10) x E_8
part of the CFT. However, it can only yield chiral spectra if the ``internal"
sector of the theory provides a simple current of order 5. Here we apply this
new method to Gepner models. Including exceptional invariants, 86 of them have
the required order 5 simple current, and 69 of these yield chiral spectra.
Three family spectra occur abundantly.
