I have 3 '06-'07 ZX10R engines.

1 - Leaned out, rod through case. This happened less than 30 laps after rebuild including CNC valve job. Have paperwork for rebuild.

1 - Oil Filter gasket failed, lost oil pressure, engine seized. A little over a season after rebuild.

1 - Oil Pickup bolt broke, lost oil pressure, engine seized. Right off the bike with ~20k miles.

There might be a water pump, oil pan, or a starter missing that I scavenged for my current engine, but otherwise they are complete.

$500 OBO. Located in Northwest Ohio.
