I'll just give everyone a cliff's note version.
Purchased used bike by enthusiast. He was the first and only owner. Claimed valve adjustments and oil changes every 1k miles
Rode the bike for 80 miles, and oil started spewing out of valve cover gasket. Bike at this point sounds real funny (loud valves?) and does not hold an idle well.
Truck bike home and replace gasket and re-adjust all 4 valves back to factory specs .002. Bike runs for 5-minutes, again--really rough and dies shortly after with a loud 'boom' from the exhaust.
Pull valve cover gaskets again, and noticed that one valve adjustment holder nut had worked itself loose. At this time, we re-adjust all four valves again, and bike starts right up.
Bike runs, but really sloppy. Hesitation issues, idle problems, etc.. So we pull valve cover off again, and check valves. All valves are ok, but CCT is worn, and metal bits and shavings in oil.
Bike at this point does not run. (will not start)
Without tearing apart the motor and digging further, that is my current conclusion.
The timing chain could have jumped a tooth... The bearings could have seized.. The valves could be bent.
At this point, I don't have enough knowledge to go further, but i'm armed with enough information, to hand over to the dealer for further investigation.
At this point, i'm expecting the worse, so there would be no shocks.
Sucks, cause the bike was a real blast to ride, and I can't wait to get it back.
