just think of how much different your girlfriend would look if you gave her the 1600. after she got the clothes off, shed be the same. i vote dump it into the bike. actually, the 750's really probably arent worth that much. id say close, in great condition, but id never pay that much for one. if you want someone here to tell you not to spend thousands on an old obsolete motorcycle, it probably wont happen. hell, my bonneville is right back where it started when i got it. sitting under a tarp in the yard. and i dont have any idea how much i put into that thing. if you dig it enough, you'll spend the $$$. im sure someone here can hook you up with the diaghram parts your craving.
