Hi guys can any one tell me what these marks are and what the drill mars are that I have marked out.... dose it mean that it is Blanced since it has been out of the factory..... It has new pistons and has had a full re-build. I bought the motor cause it had crank movment back and forward... who ever put the motor back together put the Thrust bearing on number 5 and not 4..... I have changed that but I would like to know what the marks mean if any one could help.....
