Man you've got an eye 2M!
Great pics, Bob. Let's us scrutinize. Aside from the vintage filth, and Jim's mention of the tank/head contact, all I can see out of order is a possibly degraded plug wire. If it's from mouse chewing, closely examine all the wiring. Those guys go after the salt taste in the insulation...

Your pic of inside the left cover nicely shows how Yamaha cheaped out on the round alternator cover screws. They used screws that were too short. They used M5 x 10 screws. Change them to 12's or 14's to utilize all the available threads.
Skull and Pete make an interesting point. Last September's issue of the Classic Bike Guide has a short article by Frank Westworth, (editor of Real Classic magazine - a Pommy outfit specialising in the acquisition and maintenance of classic motorcycles), where he compares the virtues and values of a "completely restored and mostly stock machine with an unrestored and mostly factory stock machine."
Frank likes the unrestored version and here is his reason,
"There was a small coven of professional rebuilders who rebuilt unrestored bikes to a considerable standard of shine. It was easily possible to rebuild a re-import and turn a considerable shilling when selling it on. But today? The reverse appears to be increasingly the case. Such is the demand for unrestored machines that it is almost impossible to make a profit from rebuilding one." (Frank Westworth CBG September 2017).
Bob, I am of course not suggesting that your motivation is mercenary. I'm sure you'll take the '77 and the X2 with you when you go, (or you could leave them to me! Damn! Going by your last photo, I'll probably go first!!). I merely point out the opinion of a learned person engaged in the "classic" element of our sport in support of the posted commentary above. Bikes like this one are hard come buy and, as you are undoubtedly aware, warrant planning and consideration.
Cheers
Nice pictures! I've noticed most of the dirt is from standing still and not from riding, looks pretty clean. By the looks of it it seemed that no one touched the bolts, nuts and Phillips head screws. It's in a great shape, no rust, untouched. I think it's very rare if you bump into a bike like this. Nice one!
Sweet find Mailman!!
I am currently looking for a 70 thru 72 in Similar condition just to have a look at.
What I would really like to know when u get it all running is how it compares to the 76 u currently have
running, handling power ride ect. Ive read the early bikes were real shakers with poor handling but theres no disputing
the fact that they are with out a doubt the BEST looking xs650,s of all time. I think its so cool that something that old (I was 9 years old when that bike was built) is still in that condition.Its like finding Dinosaur bones.Its amazing, Luv it.
The Muffler pipes and header pipes are usually shot but yours look New. Best sounding xs650,s of all time!
Do I sense another flat black hardtail bar-hopper build coming on?!!
Man I'd love to get an early model like this one.
I wonder what the sun strainer looks like?
