[QUOTE="Jman271, post: 473832, member: 25310"] The only piston I found that worked in my 02 cr125 was a Wiseco pro-lite, no rattle, the stock piston is noisy as hell. The reason they make diff cylinders, A,B. I believe has to do w/ mfg tolerance discrepancies. They run off a 100 jugs at a time, but they don't all come out the same. They measure them, if the are like .0123-.0126, they get marked an "A", if they are like.0125-.0128, they get marked "B". Don't quote me on the #'s, I'm just using them for an ex. I hope I'm saying that right- [/QUOTE]
