[QUOTE="Dan105, post: 1260406, member: 34235"] I tore the top end down on my 05 YZ250 smoker and tossed the stock piston. I then sent the motor out for porting work. I get the motor back and go to order a piston but realize I dont have the old piston to read the model number off. I know this sounds retarded but - I run stock pistons in all my bikes. When you microfiche the piston on OEM Yami site there are 4 different pistons. The manuel says the jug should be lettered at the rear above the intake but it is not. Short of grabbing a micrometer and measuring the jug, any suggestions? [/QUOTE]
