Awhile back I picked up a 1978 KZ400B with a spare 76' 400 motor for cheap. It's another rabbit hole, thus the name. It was registered and running as of late 2016 then supposedly stopped running and sat. The po apparently lost or sold off a few parts like the tank, coil, left foot rest, and shifter among other things. The engine turns but I haven't gotten as far as trying to fire it up. I'm doing the homework on it now and trying to decide if I want to sort it out.
