That motor didnt fail due to a slip fit bearing.... Or any kind of main bearing issue from what I see in those pictures...
My Personal vote.... Cast piston strikes again

In my 25+ years of using cast OEM piston's i've never seen one fail for no reason. I have seen many cast pistons (and forged) fail due to excessive wear and "skirt slap" against the cyl walls.... I personally have much respect for the consistant relibility of OEM cast pistons. One things clear in the pic is that that engine failure was a WFO, catastrophic piston granade to do that much extreme damage.. (strictly just my opinions)

It was worn, that?s why i sent it to the "machine shop"
why did they not fix it

Well, they did something.
I had a worn journal of the left main bearing.
It could be felt with the fingernail.
Now the area is shiny, maybe just polished or so.
The notch is still there, but the bearing also slides over the seal-area which wasn?t damaged?!
The bad thing is that i just didn?t have a close look at the journal after the "repair", was blinded by the shiny surface.
Removing it again will damage the right bearing...
Motorrad,
How much play did your bearing have?
Was it a k5 (so you had to glue the bearing and insert crank into seal at the same time)?
kwakman:
tschisi, how did you resolve your seal seat damage?
tschisi:
No fixing needing.
As the seat itself is undamaged, and only about 1/5 of the stop is broken out, this doesn't effect the sealing function.
Confirmed by a kawi-mechanic.
The stop just prevents the seal from getting pushed out...
kwakman:
your lucky.dont forget to use case sealer round the out side of seal.K.
