Piston numbers

[fox_forma]

Been searching around for a little and got most of my answers need but still need help on the final part.

 

I have been trying to identify my pistons but can only go so far. Each piston has the markings 513M06500 which I have tracked down to being wiseco 65mm pistons.

 

The part that has me confused is each piston has a different number above that. One piston has 6552K and the other 3245J. Can anyone identify what those numbers mean?

 

Thanks

Not really sure, but I think they are the serial numbers for the pistons, or some kind of identifier number. The 513 is the series of the piston, and the 65 is the bore size its made for.

I just found it odd that both numbers are completely different. Would like to know exact size of each one or whatever those numbers mean cause I know they also identify with letters such as the K and the J.

yeah after 3months they finally showed up. I just want to know what the numbers mean before I go throwing them in and causing some issues.

Honestly man screw you.I offered to BUY YOU NEW PISTONS SEND YOU BANSHEE PARTS LIKE MY WHEELS AND TIRES And all that stuff you just had to measure.I know it was a fuked up shit but if they were in my hands when I sold them they would have been their in 1 week.He never knew you wanted the pistons and I guess I shouldve told him.But dont say I screwed you or anything because I didnt.That same week I prolly sold another 5 parts on here and they were fine.I didnt know that would happen oviously but hey atleast I didnt screw you.

first off man, nowhere in my post did I bash you or anything so telling me to "screw myself" I dont appreciate. I also dont care if you sold 50 other parts on here. I was simply letting you know that after this whole wait period I finally got my parts that were suppose to be here in November. And yes you did offer to buy new pistons for the bike but I was nice enough to let you talk to your damn builder to clear it up so you wouldn't have to fork out the extra cash on something that was your builders problem. So saying "screw you" is like a kick in the face, I didn't blow your spot up on here when the parts never showed up did I? I easily could have but I gave you benefit of the doubt that you were clearing everything up in a timely manner. Guess next time I will just be a dick about the whole thing.

 

Now back to the numbers, the reason I am asking is because they are different on each piston and I want to know if its a size difference because one of the pistons almost feels to big for the one cylinder. I want to make sure they are basically the same size and not off, that is it.

take your cyclinders and pistons and get them mic'ed. I could be that either the cyclinders are not both the same size or maybe the pistons are different. I think those other numbers are batch numbers, and having one from 2 different batchs isn't a bad thing.
