Right now I've got five bikes with titles, but only one runs
1981 Honda CX500 Deluxe frame, with a 1980 CX500 Custom engine and frontend (and tags

), tank and headlight off a '79, tailsection off a '78, mufflers off an '82 GL500, rear shocks off an '06 Sportster, turn signals off a CB650 of unknown vintage, clutch cable adjuster from an old GPz that got written off by a fire, and a couple brackets cut out of an old Compaq Proliant case.
Fear the 1-bike Armada!
