crank let go. as for the sleeve cracking thats about rite for a kaw-e . they are very thin by the transfer ports. most of them are cracked with out blowing up. hard to tell but it looks like lower rod bearing failed. got any gold or copper spec on the top of the piston?

Interesting on odd sounds turning over engine. No gold or copper color either.

 

[ryan]

could b a wrist pin bearing then
