The piston ring gap for a Yamaha G16 typically ranges from 0.008 to 0.012 inches (0.20 to 0.30 mm) for the top and second rings. It's essential to check the specifications in the service manual for your specific engine model, as tolerances may vary. Proper gap measurement ensures optimal engine performance and longevity. Always use a feeler gauge for accurate assessment.
.012" to .020"
You mean a piston ring. It seals the gap between the piston and the chamber in your engine
Piston ring gap.
End gaps, or ring gap
To install piston rings on a Yamaha Breeze 125, first ensure the piston is clean and the rings are oriented correctly, with the marking or gap positioned as specified in the service manual. Gently compress the rings using a ring compressor or your fingers to fit them into the piston groove. Carefully insert the piston into the cylinder, ensuring the rings do not get pinched or damaged. Once the piston is in place, you can proceed with reassembling the rest of the engine components.
The split or gap in a piston ring is called the ring end gap. It allows for the ring to expand and contract with changes in temperature during engine operation, ensuring a proper seal against the cylinder wall.
You will need feeler gauges, a ring spacer and separation tool, the correct specs for their correct placement on the piston and the gap specs.
Stagger the gaps so they don't line up.
The DNJ ring spec. information, printed on each compression ring (located next to the piston ring gap), is installed facing the top of the piston for both the top (#1) and middle (#2) compression piston ring slots. The oil control ring can be installed just like any other oil control ring in the bottom (#3) piston ring slot.

Gently.Answer:Once the piston is removed from the bore the ring or rings are exposed. Each ring will have a gap or split in one place as it goes around the piston. This gap is spread open and the ring lifted off the piston.If you need to reuse these rings or the pistons they are for you use a special tool.If you don't care gloves are recommended and fingers will do the job.Careful! The rings can break when flexed like this and create flying sharp steel pieces!
There should be a arrow on top of the piston close to the pistons edge. Your top ring's gap should be on same side as arrow. Then alternate next ring 180 degrees from last gap. The arrow should facing forward when installed into the jug.
