Upgrade for 61SH: Piston, Ring & Liner Set YSS6205S by YS Engine  [YSS6205S]

61SH Service Set - Piston, Ring & Cylinder Liner

The YS Engine YSS6205S set supplies replacement piston, piston ring and cylinder liner parts for RC-scale 61SH glow engines. Use the kit to correct compression loss and diminish blow-by caused by worn internals.

Made for hobbyists performing routine engine servicing, the kit is suited to mid-life rebuilds of 61SH units. Always check mating surfaces, confirm ring end gap and assess liner roundness prior to final assembly to ensure dependable running.

When compression tests or increased oil use indicate wear, replace the piston, ring and liner together to maintain uniform bore geometry and stable engine operation in RC models.
