Overpriced? Yea or Nay? Feels like it, but I have zero knowledge of restoration. It looks like a job done very well (from what you can see from pictures).

Wow, 13,500 for a 73 CB750? I don't see that happening. It's like most restoration projects, buy a bike for 1000, add $5000 in parts and hope for something for your time. In reality, it's a 73 CB750, IMO it's hard to get it to break $5000 no matter how well it's done. It's very common and although it's an ok bike, it's not something that everybody lusted after. As bigpoppa brought up, you need to look at your pricing compared to what else people could buy for similar money (which in this case is almost every bike made between 1973 and 2015).
