check the 3 phase wires going into the reg rec (these are on AC with a multimeter, quite likely its your alternator, you`ll see the plug that goes into the rec from the generator casing side of the bike.
Quite likely your generator windings are burnt out, or you have replaced with another dodgy reg/rec. The low voltage across the battery makes i tlook like a reg/rec or generator or wiring between the two the possible issue.
