47.6mm MInarelli Gasket Set

47.6mm Cylinder Gasket Set for Minarelli 50cc Engines

This set is made for 50cc 2-stroke Minarelli engines and works with the Hoca Ceramic Big Bore Racing Kit that has a Nikasil coating. The package contains an o-ring for the cylinder head, a base gasket, and an exhaust gasket. It is one of the simpler Minarelli 50cc / Yamaha jog scooter parts to swap out during routine service or when upgrading an engine.

What's in the Box

You get a cylinder head gasket, a base gasket, and an exhaust gasket. Each one is built to keep a snug seal and let the engine run as it should. The head o-ring blocks leaks between the cylinder head and the cylinder. The base gasket holds the cylinder against the engine casing. The exhaust gasket seals the join between the exhaust pipe and the cylinder, which matters for smooth exhaust flow.

Fitting Tips

Before fitting the new gaskets, wipe the mating faces clean and remove any leftover old gasket material so the seal can form properly. These parts are usually replaced whenever the engine is rebuilt or serviced, which helps avoid compression loss and possible damage. Tighten everything to the manufacturer's torque figures.
