Nice wheels and forks by the way 
If you can get the BMW fuel tank it will likely be aluminum and a sight better then the rusty old Honda ones.

Highly advise ditch that tank, post a photo of what's left of your frame, because your frame has no lateral rigidity with the rear triangulated section removed, what's left would crack in use now that you put serious tires and suspension components on it, & no way would that pass a tech inspection for road or track use in any developed country unless you put some lateral frame support on there between the steering head and the rear swingarm support bracket.
Your bike is actually very typical CX unless you scratch build a new frame of your own design.

The problem with your fuel tank is that it is way too early to be on there, unless you are just building an art project. The fuel tank is ~40 pounds of dead weight load, it's not a frame member, it adds stress to the chassis not strength and it's useless if the engine doesn't run.
How pretty the metal polishes up would be no surprise and the least of my concerns, if your engine doesn't crank over with healthy tested compression you are looking at an engine rebuild and that's not an easy engine to work on. You live in Britain, don't they have mandatory vehicle inspections there? The Honda GL/CX 500 had marginal adequate frame strength before you took an angle grinder to it, although I have seen worse, I seen one where the guy cut away even more of the frame thinking the engine is there to hold the wheels on. ... Fact is that engine is going to do everything it can to go in a different direction then the rest of your bike and the part you hacked off does a lot more then provide somewhere to mount a saddle. If your goal is to build yet another fenderless rolling indoor art project it will work just fine, if you are building a motorcycle for a human to actually ride I would fear for their survival, although I suspect the chance of such a motorcycle ever seeing road insurance, a license plate and being ridden to any extent is slim to nil. Best luck with your art project Dan

from here it looks like a chunk of half inch threaded rod for a steering stem

My strange eye is drawn to different things when I look at a motorcycle. M8
