Grab it, the CB and CM twins are becoming fairly popular. It probably won't make much of a track bike for sure. If you can title it and make it an ugly runner without a big hassle it'll fetch upwards of $500 in most areas. These bikes are pretty popular with the bobber crowd, but a few have caffeinated them. If you part it and it's got good pipes and a good tank shoot me a pm.
The 'C' means it's got comstars... a 16" rear and an 18" up front, it's probably got a single disk front and a drum rear, and it's probably an 82 model.
