Also I sold the crank, it was good enough in a regular motor and I sold it also.

I just didnt want to take a chance with these parts in my ski. Mine is heavily ported and I didnt want to take a chance.

Hi.
if I had cases like that in an M/C engine they would have been out of the window .. so I guess an inner main bearing broke up and trashed the lab. which tended to be on the CS2E (sorry if anyone has a CS2E it was a problem). There are many a time I poped a crank apart fitted the 2 inner mains & lab seal .... It was just balancing the crank afterwards
