Yeah sure enough my end gap is ~.022-.023". Definitely need rings. I dont have a lot of hours on this top end and i noticed some very small pit marks on the cylinder wall. Not too happy about that. Also see the crank is covered in oil. Need to see if thats transmission oil or if the petcock didnt seal right and its 2 stroke oil left over after the gas dissolved? Everything always turns into a bigger job hahah
