79’ 650 New Reg/Rec Causing Electrical Issues?

No, the timing marks shouldn't be there. The reference mark on the rotor looks correct, at about the 5 o'clock position from the magnet if the magnet is at 12 o'clock .....

That leaves only the keyway and/or mounting. Maybe the keyway was machined in the wrong spot, or the rotor was mounted without the key in there.

As far as the reg-rec issues go, I'd say your new combined unit is bad. It's not uncommon. Most of those units are cheap, Chinese junk, even though they can cost quite a bit. Many of us "roll our own", so to speak, using an automotive regulator and a rectifier from the electronics world. Much cheaper and more reliable ......

I just pulled the stator last night. You were correct. The key was not there and exactly where the new timing marks were made lined up with where it would have been positioned if the key was there.
 
There is a lot of Chinese rubbish out there in the aftermarket for components like points, condensers etc.... I actually had brand new points and condensers that were bad. The issue I had was with the points not reliably closing again when opened. In the end I admitted defeat and converted to electronic ignition. Not saying that is what you should do but I'm very sceptical of a lot of the aftermarket spares out there. If your points are not new Yamaha parts, I'd be wondering about them. Hope that helps.
I might look into an electronic ignition but I just replaced my stator with a PMA. I’m gonna give it a shot. Especially since I butchered the old stators wiring harness to get it out.
