To assemble the GasGas MC 125 engine, you will need to loosen the screws that secure the engine block to its housing located at the front of the motorcycle: once the support screws are removed, you can proceed by loosening the intake manifold screws and disconnecting the cables connected to the engine.

Once the engine is freed, you can proceed by opening the engine block after loosening the screws that secure the cylinder and the cylinder head: this will give you access to the piston, which must be removed from its seat to access the connecting rod and the crankshaft, replacing the necessary components.
