Need to know these things more than ever cuz i have even more reason for finding a motor, and more motor if at all possible.

Yup, the plug porcelain is gone!
Note the impact damage, so either it fell off and banged around in there or something else gave and did it...
Wont know the root cause till its dissected but lets hear your guesses...
Here are the facts, cool night 20°C
Didn't much let it warm up, was in a rush home to beat the rain.
But not unlike usual, i ride full throttle, red lining it with few stops on the 8 mile 15 minute ride, only this time i made it less than 2 miles when it died...
Pulled over, pushed it back...
Never noticed a white plug or my bike running lean otherwise, even before bumping the main jet to 110 last fall.
And as it was only 3 minutes in im not thinking heat.
It was a NGK DPR8EA 9 plug from autozone, a match for the D8TC I believe.

This guy with a Harley Shovel in what sure looks like a stretched DF250RTB-B that I posted in #4926.

well truth is im at the same place with the savage as i was in the winter, as ive been wasting time rebuilding my old ford.
just had to drop the transmission to get a stuck axel out..
I see now, that does look like the RTB frame.
That was my original intent with getting the LS650, but after measuring it was very tight... and I thought, why destroy a perfectly good bike, when i have everything needed to make another.
That said the only silver lining for me just now trashing the engine would be having to replace it with something worthy like that
