Model: Sym Cruisym 125
Part: Engine

To remove the engine from the Sym CruiSym 125, loosen the bolts securing the engine block to its housing, completely removing it and disconnecting the relevant pipes and connectors. Once the engine block has been removed, proceed to loosen the bolts securing the cylinder head and valve cover, allowing you to remove them and access the piston contained within: this can be detached from the corresponding connecting rod, enabling access to further internal components and potentially replacing them with new parts.
