Message: [QUOTE="steve.emma, post: 1087237, member: 36039"] all bikes need some side to side play in the rod otherwise they would seize! its the amount of play thats the key, measureing the rod bearing clearance between the thrust washer and rod is a good way to determine the amount of wear in the lower end without disassembly. for example my clymer manual states 0.25-0.27mm for a 90' yz250. what you really dont want is for there to be up/down play (worn bearings). if you check the rod side clearance ands its excessive then you will need to look at a crank rebuild etc..
