Kick It!! My LI125 project in Show Us Your Lambrettas Posted October 2, 2018 A true .003 clearance is going to give a ring gap of .009423...Pi theory. .009423... ring gap is what you want, or .0010 if you want to get all technical? It'll prolly run as it's honed, with new rings , but she's going to rattle. Ring's aren't going to seal 100%, barrel is scored. But it will run.
