Yamaha OEM specs are:
Top Ring - .008"-.012"
2nd Ring - .014"-.020"
Oil Rings - .008"-.020"
CP Piston specs are:
Top Ring - .0187" (There's a note in the manual that says don't go under .016")
2nd Ring - .0224"
Oil ring - No less than .015"
Here's what I measured for end gap in a cylinder with brand new Nikasil and a fresh hone:
Top Ring - .012"
2nd Ring - .018"
Oil Ring 1 - .015"
Oil Ring 2 - .014"
Does anyone have any input as to what numbers I should shoot for? Do I follow CP's recommendations exactly because the gaps seem big? I plan to make sure both oil rings are .015"-.016" unless I should go bigger for some reason, I'm more concerned about the top and 2nd ring.
