12. Even though the Wild Things 103/3.875-inch bore pistons are brand new, Kazoo checked the piston ring side clearance in several locations to make sure everything was to spec.

13. With the piston ring side clearance, Kazoo then checked piston ring end gap. Improper ring gap can have adverse effects. Too tight of ring gap can lead to the ring edges to abut against each other at engine operation resulting in ring breakage, cylinder scuffing, and/or piston seizure. And just like improper piston ring side clearance, excessive ring gap can lead to high oil consumption, blow-by, and reduced engine efficiency. The rings were a little too tight so the ends were lightly filed down until they met spec. He then cleaned the inside of the cylnders as per the provided instructions.
