I just read the thread Chris. There was a little "dog piling" going on considering you had just lost an engine. Here's another one for you: Why didn't you change the CCTs you big dummie?! Haaa! I hope you know I am kidding.
Glad your bike lives on. Do you have another ride now?

My nighthawk is having a few small issues though. Trying to get it sorted soon.

That Nighthawk is one of the nicest bikes (with the exception of the Superhawk) that Honda ever made and it was a 700cc tariff buster to boot. I am glad to know that the SH was saved.
I don't mean to dog pile on ya but you should have had a clue when you drained the oil and a whole bunch of slag didn't dribble out.

My two favorite bikes so far are the superhawk and the nighthawk. I will own both one day. Superhawk is next on my list. And then I want a Kawasaki z1000 and I will be set. Haha. Here's the nighthawk

I had a close cousin to the Nighthawk back in (I think) 1984, a CBX750F. Same motor, longer stroke, but chain drive. These are one of the few 4-cylinder Honda's with self adjusting hydraulic tappets. Make sure you keep fresh clean oil in that engine! I borrowed one (I was working part-time at a Honda dealer) and it ate a main bearing.

Okay, I'm a youngster an I've had my super hawk for about 5 months. It's my dd. Its a 1998. It also has 34k miles it. You described exactly what happened to me. 65-70mph an off it went an the back tire locked up. Lucky i ride with a couple fingers on the clutch at all times so i saved it. No noises or sounds. There i was stuck. But it stills goes in gear, My lights work. It didnt leak or smoked at all. I just spent over a grand on tires, brakes, seals, rotors, an annual service. Is it cheaper to buy an engine or fix it. Any advice is appreciated in advance.

I am going to say "it happens!" That's all it just happens. A guy in South Africa, on the VFR forum had his 2010 VFR1200 tie up with a rod bearing issue. I myself have just finished building a VTR with a bottom end bearing issue with no cause that I could find. It just happens sometimes. The tolerance are so close, maybe they get them too close sometimes. Who knows. I found it cheaper to fix the engine even after buying two used cases, a used crank and a used oil pump plus the related wear parts like rings, bearings and gaskets. I think I had less than $500 in the build and people were asking $800 and up, plus shipping on eBay.
In answer to you second question:
Yes but it usually makes a lot of racket before it does.
Do this:
Drain oil and check for crap. No shavings and stuff equal good news.
It it were me, the next thing I would do is pull the plugs and with a wrench carefully try and turn the engine backward. (This is clock wise as your are looking at the bike from the left side.) If it stuck a valve it's possible that the crank will rotate backward. Before I swapped engines I would pull the heads and have a look. That's pretty easy and it really gives you a definitive idea if the trouble is in the bottom end.

Absolutely possible and most likely happened by the time you hear the knocking noise from the same cylinder that you lost the CCT. The CCT's don't just go together, remember you have everything of two on this bike, including two timing chains, only one will go at the time and more likely the rear first.

If we're still being asked to "Name that bike", I think most of it is a 1990-odd CB750F, based off the CBX750 that I owned "back in the day". But it is a real Frankenstein, the tank, fairing and front wheel are off something else. Is the tank off a Superhawk?

That would be the model we did not get here in the US mate, instead we got the most basic version as followed, pay attention to the details:
and yes, tank is off a CBR900RR, front wheel, you should have picked up.. it's off a VTR, rear wheel also off a CBR900 and on and on...
