That's pretty sad. Give him our condolences.

You would have to think that in at least one of the accidents the engine must have run on its side for a time.

As you may have read in my (currently stalled due to the lack of one part..) rebuild thread (Pat's Engine Overhaul) my big-end bearings were in great condition after a reasonable mileage.

That's what makes me think your friend's issues are probably due to his bike running while lying on its side, with some attendant lack of oil supply.

Yes, it's definitely possible that it ran on it's side for a bit.

Pat, how long would it take for damage to occur from that? Seconds or minutes?
Depending on revs, not long. Not minutes. :bawling:

Only as long as it takes to clear off the residual oil, then she's running fairly dry.

Plain big-ends need a high-pressure oil delivery. When that falters they cook pretty quickly.

No balls or rollers reducing the friction in there.
