Piece of the frame fell off - How boned am I?

Hey all! About a month or two ago, I was riding my '99 VFR800 and stopped for a break. I had the bike up on the center stand and noticed that when I revved the engine, a screw hidden under the cowling would rotate. "That's weird, that shouldn't happen...", and then I soon discovered to my horror that a piece of frame has indeed fallen off. More specifically, it (forgive me if I'm using the wrong terms) seems to be the front left (when looking at the back of the bike) of the 4 bolts that connects the main frame to the sub frame (the black frame that holds up the seat and such). The other 3 bolts seem to still be in there fine. And, while I do have the screw, I don't have the piece of frame that fell off, so welding it back on won't work. I would assume if I took it to a welder or metalworker or whoever, they might be able to fab up a piece and weld it on, or at least engineer up some sort of bracket that could hold the two in place. Worst comes to worst, I could buy a new frame off eBay and maybe transfer the vin plate. (Or don't, and just live with it...)

If I hadn't noticed the spinning screw, I might have never noticed the missing frame piece honestly. The bike still feels fine to ride. But, it's retired to the garage now, as any frame damage = not safe to ride in my book.

Also-- to anyone who has stripped their 5th gen down to just the frame, how hard is it? How much time does it generally take? I'll be attaching some pictures to hopefully help you, the fine reader of this forum post, understand the situation. Any additional suggestions are welcome.
Thanks for your time <3


Hoping to getting back to riding soon

 

Well now that is a bit ugly. The only good thing is that the joint is just for the seat subframe so not critical to keeping the wheels in line, but you'd certainly want to avoid pillions, heavy loads or jumping hump-back bridges. I have no specific knowledge but I would imagine that you could get a chunk of alloy welded on and drilled out to repair that area without compromising the rest of the frame.
