Wow, man what a kindness! Thank you, Sir!
This was my mostest-worstest oil change of all thirty. Drain plug pulled its threads out in bits/ first stuck oil filter, ever/ sump fastener that holds the left side, rear aspect of the sidestand index plate pulled its threads (all in one coiled mass).
As many of you already know (or suspect), when my Sport goes down (for whatever reason), I become, er, rather afflicted . . .
My local (O'Reilly) auto parts store had the full M10-1.50 Stanley "Heli-Coil" kit for the drain plug. Heat gun and a friction surface (100grit paper) inside a strap wrench had the crumpled filter loose. Come first thing Monday morning, my local "Fastenal" store set me up with the M6-1.0 repair kit for the sump. It was really sketchy to get the Sport jacked high enough, then drill and (STI) tap the hole vertically upward. So, nope, standard M6 tapping will not work; must be "STI."
I did, finally, prevail and had the Sport back in action in under 48 hours.
The upwardly drilled hole is not perfectly aligned, but stabilized the sidestand plate and the sump does not leak.
Once again, @Bob Maynard , thank you kindly for the generous and trusting offer of help!
