Nice work and as for the engine, any Unit Twin Triumph motor is pretty much the same as another with small differences over the years. I'm rebuilding my 1970 engine with a 750 kit, I should have some photos this week for my thread. I've been busy with life but this week should have progress.
The new wiring harness you are doing should be a great improvement, my bike got one when it was restored 20 years ago and it's still like new. I discovered a great YouTube channel for rebuilding my engine, it would be helpful for you if you rebuild the 750. Probably videos for other operations as well, these guys are super thorough and great videos:
There are several chapters adding up to many hours, this just happens to new the one I'm on now.
