Replacement Cylinder Liner for 61H RC Engines - YSR6205 Compatible Part by YS Engine  [YSR6205]

Service liner for 61H-class engines

The YS Engine YSR6205 cylinder liner is supplied as a spare component for 61H-class model engines. Its role is to replace a worn barrel section to renew cylinder geometry during overhaul, with the focus on fit and workshop procedure rather than marketing claims.

Standard installation steps apply: remove the cylinder head and piston assembly, extract the existing liner, inspect the piston and bore for wear, then press the replacement liner in using correct tooling. Ensure gasket faces are clean and reassemble using appropriate torque values for your engine variant.

As part of tuning and upkeep the liner is a consumable service item that restores compression and bore form after wear. Maintain service records and inspect mating items such as the piston and rings to determine whether they should also be renewed.

Fit this liner during scheduled rebuilds to bring cylinder condition back to specification and support reliable running; confirm correct fit for your 61H-series engine before installation.
