Ok, now I'm putting the cylinders that I got in the deal. Wasn't planning on selling these but now I'm going to since I'm not going that route. Really don't know a whole lot about them but ill try and post as many pics of the porting on them as I can. They were ported from what it seems like is read on the side "Will JC." They are 66mm bore. They look to possible be a drag port and I'm looking for a nice dune bike setup so I'm going to port my cylinders I have now and sell these ones.
That is all I know on them and they seem to be in good condition. I'm sorry I don't have a lot more info on these but was told the porting on these was pretty good.
Looking for 300 plus shipping obo
