the big bore cases are taida. The stock style gy6 cases have been bored up to 63mm but its not reliable at all. Cylinder walls get way to thin for a air cooled engine, and the studs are exposed to the cylinder with no or very little meat which these bore kits should not even be recommended if you ask me. My next build will be a taida engine which allows for up to a 67mm bore!
