Just bought a used cylinder and piston from an 87 trailboss (but I dont have it in my hands yet). cylinder wall looks great smooth with a mirror like shine. wondering if i should consider putting new rings in before putting it all together. if so...should i try to put a cross hatch on the wall.... ball hone or 4" three stone ? andbody got a good method they would be willing to describe for getting the cross hatch?
