I'm planning on punching my heads while I have them off due to bad rings and rocker gasket leaking. I need some advice from you buell veterans on optimal displacement I should shoot for and what pistons have you guys used or would recommend. The little research I've done is showing 10:5.1 compression is good with these motors? How much would you need to bore your cylinders to reach that? My motor guy will be freed up in 3 weeks so I would like to get pistons and gasket kit ordered and ready. Your expert advice will be greatly appreciated. Thanks
