Crank case set includes piston, Rings, Rod and crank with perfect play up down also side to side fully inspected no cracks no blow by no warps simply a light layer of carbon build up on the piston as expected from a used part. Both right and left inner cases are included perfect for a project this engine was originally purchased to replace the cases on a 2012 that had a stripped drain bolt but it was sold to us instead as the original owner realized he bought the wrong year cases as the vin reads it is from a 2008 KX450F Both cases are in great condition with the bearings included everything in the pictures comes with the cases we can separate them aswell if you would like us to split them for you we will also clean them for you if you would like! This also comes with a bag of miscellaneous hardware timing chain as-well as other small Internal components that may definitely come in handy for your project!
