Well I managed to blow mine at 23500 -she had heart -- unfortunatly thats no match for 2 qts shy oil --ouch , after a nice wheelie I came down and there was the knock -- took it apart and the #3 cyl piston arm bearing was gone!! but fret not all I got a new (used) engine coming in a few weeks------ which if anyones selling one let me know if ur in the chicago area I still havent purchased it..
