YS Engine YSS8110 Connecting Rod for 61ST-2 Series Engines  [YSS8110]

Service connecting rod for 61ST-2

The YS Engine YSS8110 connecting rod is supplied as a direct-service spare for YS 61ST-2 series glow engines. In an RC internal combustion engine it transfers piston motion to the crank while preserving alignment and durability under load.

Made to match the original part fit, this component replaces worn or damaged rods on 61ST-2 engines and maintains correct big-end and small-end interfaces to protect timing and compression geometry.

Installation notes: check the crankpin and wrist pin for wear before installing the new rod, renew bearings or bushes if needed, and verify endplay and clearances after assembly. Carry out a measured running-in and regular inspections during break-in and tuning.

Service impact: the rod does not alter engine power output by itself, but a correctly fitted rod supports stable combustion and predictable tuning during bench testing and club-level competition use.
