Description: 2 Stroke Ring
Overview:
The Piston Ring Set for Power Pro / Maruyama PS110 Big boy 2 Stroke Engine is a Genuine Power Pro part designed to restore and maintain correct cylinder sealing. Supplied under OEM number MAR-BIG02-12, this ring set fits the Maruyama and Power Pro PS110 Big bore engines, protecting compression and helping the engine start cleanly and run efficiently. The rings are manufactured from durable metal for reliable service in vintage powerplants that see intermittent or regular use. As unused old stock, they may show minor surface tarnishing or storage marks, which do not affect performance. Correct ring sealing reduces blow‐by, stabilizes idle, and supports power delivery when the engine is under load, making this set a practical choice for routine servicing.
