The Honda 130B1-896-003 Piston Ring Set (0.25) is a genuine OEM oversize piston ring set designed for G100 horizontal shaft engines, BF2 and BF20 portable outboard motors, EM500, EM600, and EM650 generators, EX650 and EX800 generators, F200 tillers, HR17 lawn mowers, and WA15 and WB15 water pumps. As a direct Honda OEM component, this ring set is manufactured to the exact specifications required to restore proper bore sealing and oil control after a cylinder rebore or oversize reconditioning. The (0.25) designation identifies this as the 0.25 mm oversize variant — confirm your cylinder's current bore size and rebore dimension before ordering to ensure this is the correct set for your application.
Key Features
- Oversize Bore Sealing — engineered to the exact 0.25 mm oversize dimension, restoring compression and oil control to a freshly rebored cylinder where a standard-size ring set would not seat correctly
- Genuine OEM Construction — Honda OEM rings are manufactured to the ring-gap tolerances and face profiles specified for these engines and machines, ensuring proper break-in and long-term cylinder integrity
- Broad Cross-Equipment Fitment — covers G100 horizontal shaft engines, BF2 and BF20 portable outboards, EM500, EM600, EM650, EX650 and EX800 generators, F200 tillers, HR17 lawn mowers, and WA15 and WB15 water pumps, all sharing a common bore specification
- Variant Verification Required — the (0.25) oversize designation is the critical matching point; Honda also supersedes ring sets at production breaks, so check your unit's serial number against the fitment table before purchasing
- Compression and Oil Control Restored — worn or broken piston rings allow combustion gases to blow past the piston and oil to migrate into the combustion chamber, causing power loss, excessive oil consumption, and smoke; a correctly sized replacement ring set returns the engine or motor to its designed output
Piston rings form the dynamic seal between the piston and the cylinder wall, serving two critical functions: they contain combustion pressure above the piston to drive the power stroke, and they scrape excess oil back down the bore to prevent it from burning in the combustion chamber. When rings wear, lose tension, or break, compression drops, oil consumption rises, and the engine or motor produces blue smoke and diminished power. This set is sized at 0.25 mm over standard to match a cylinder that has been bored out to remove wear, scoring, or taper, and installing the correct oversize ensures the rings close against the bore with the right tension and gap for a lasting, effective seal.
