I cracked a bearing... somehow... LOL
and on my last oil change, I had plenty of particulate
"sand" in my oil. I'm actually thinking of going back to my
stock airbox and taking off the KKM for a bit.
Which BTW has been regularly maintained, with cleaning and oiling.
It could be my cold air feed from the ground.

Yea I believe what Demon said there, I am sure its not the sand we are looking for.

But another thing, how does sand and hard right turns equal bearing failure? I understand the right turns. But I am not sure how the sand could become unloged so quick and flow downstream. It would need alot of oil to help it move, and if there is oil there than I would assume it would protect the bearing, Unless the sand is trapping the oil and not letting it get to the bearings
