Service replacement: FS-200S head gasket, 2 pcs

The O.S. Engine OS44514100 gasket set is supplied as two pieces for use with FS-200S and FS-200S-FI engines. This replacement gasket seals the cylinder head to the crankcase and is a normal wear/service item when the head is removed for tuning or maintenance.

In service, the gasket secures compression and preserves the intended head height, both of which affect idle consistency and overall power delivery in nitro RC engines. A new gasket on reassembly prevents leaks that can shift mixture and complicate tuning.

Fitment tips: ensure all old gasket residue is removed and both surfaces are clean, align the gasket accurately, and tighten head bolts in the specified sequence and to the correct torque. Check for any signs of leakage after the engine has been run and cooled.

  • FS-200S-FI

Does OS44514100 come as a two-piece pack?

Yes, the OS44514100 gasket set is supplied as two gaskets per pack to cover standard head servicing on FS-200S and FS-200S-FI engines.

Will a new gasket affect my engine tuning?

A fresh gasket restores correct head height and compression, which helps return idle and peak performance to predictable values. If you are tuning, expect more stable and repeatable results after fitting a new gasket.

Any cautions when tightening the head bolts?

Follow the engine manufacturer's tightening pattern and torque figures precisely. Over-torquing can crush the gasket or warp the head, while uneven tightening can cause leaks.
