Hey guys! My bike has been ridden for around 350-400km and started having some loud rattling sounds. I've run it at 20:1 for a tank and then 40:1 with chainsaw mineral oil. Upon opening it up I found pretty bad scoring of the cylinder. What could have been the cause of this and do I need to do a whole top end replacement ?
