This is off of an 08 yz85 I bought to flip. Motor was locked up and you can imagine how hard it was to get the cylinder off!





 
cheeesus :eek:
what is that pin from embedded into the cylinder wall ?
 
I am thinking the wrist pin. I havent taken it apart yet. I already have another top end for it. The crank is still locked up and I suspect the cases are cracked too. I have a spare set of cases too.
 
Mmm, nice going....
Looks like a failed conrod rod bearing.
How deep is that damage? Think it can be bored out?

It's a plated cylinder. If you look closely you can see it cracked the whole sleeve. A 2mm overbore cylinder came with the bike and I will use that one. This was one of the bikes that came in the package deal. 03 RM65, 03 KTM65, and an 08 YZ85 for $700.
 
ive seen them a bit worse. but the ones ive seen, the piston separated from the crank. still, that looks pretty bad.
 
Holly crap..

Looks like you can see cross hatch in the cylinder from a recent hone???
