YS Engine 61ST-2 Connecting Rod YSS8110  [YSS8110]

61ST-2 Connecting Rod Details

The YS Engine YSS8110 connecting rod is provided as a spare for YS 61ST-2 series glow engines and is designed to transfer piston motion to the crankshaft while maintaining alignment under running conditions.

Offered as a direct replacement for worn 61ST-2 rods, the component preserves the original big-end and small-end interfaces to protect timing and compression geometry during service and rebuilds.

Fitment advice: examine the crankpin and wrist pin for signs of wear or damage before fitting, replace bearings or bushes where needed, then check endplay and clearances once assembled. A careful running-in and periodic checks during tuning will confirm stability.

Maintenance impact: while the connecting rod itself does not change the engine power curve, a precise replacement supports consistent combustion and more repeatable tuning during bench testing and events.
