78 pistons

[Dirty]

Hi all, wondering if anybody could tell me the difference in 78k and 78ss stock pistons. I had a "valve to piston problem"   in my 78 K last year so I ended up scoring a 78 ss on Cl for $300 best part is the po told me it had a 915 in it but wasnt for sure. He got it with a lot of other bikes so he just fliped it on Cl. >So the suspence was killing me so I had to pull it apart!
Well its either the smallest 915 bore or its stock!   Yep its stock bore! but this one has dome pistons. Wondering if those are stock? Ive only had my K apart. Thanks, Dirty

Thanks Piute, I do remember seeing that but I guess I was just looking at valve stuff. Thanks. BTW I knew you'd be the first to reply! Being a "F" man!!
