$250 shipped I'm selling a ported 52mm KS cylinder for a Stihl 064. Port work was done by MMWS 1 year ago. I've maybe ran 2 tanks of fuel thru it since the work was done. The saw itself is real low hours so I'm sure it looks great inside. I don't have any pics of the work but I'm sure its flawless. If someone is a serious buyer I'll take it apart and send you pic. I have another cylinder to replace it with. I don't use a saw of this size often and I could use the money more. Thanks
