Manufacturer reference: YA693 — Brand: LOS ANGELES SLEEVE
Replacement sleeve dedicated to the YZ125G from 1980, designed for the refurbishment of the top-end of motocross machines. This sleeve is aimed at riders who are restoring their engine after wear or repair: it allows for a compliant bore to accommodate the piston and rings, as part of an engine overhaul or rebuild.
This part integrates into the top-end during a cylinder refurbishment operation. It is intended for demanding workshops and DIY enthusiasts who are replacing a worn or damaged sleeve to regain the necessary clearances between the piston and cylinder. Before installation, check the compatibility with your cylinder numbering (3R3 / 3N8) and consider having a professional handle the installation to ensure tolerances and adjustments are correct.
