The work you'd have to do to mount almost any other engine is hardly worth it, when you could start with that engine's original frame cheaper and easier (almost certainly)
i remember what ashman said about mounting a commando engine in a featherbed frame,
~ "trace out some engine mounts & bolt it up"
dude in quebec was selling 3 complete kz75O twins for 150 bux each, engine choice isn't set in stone, at least a 16" rear is tho, interstate tank & maybe high rider bars, prob see how vetter bags look
not lookin to spend much on a bare frame or worried about originality, rather how cheap to get roadworthy,
there is of course a highly developed xs650 iso mounted yamaton out there, not sure if the kz750 twin would even need the iso rubber mountings seeing as it's counterbalanced
what are the indicators of a 71 frame?
