To disassemble the engine of the Sym Joymax 300, you need to loosen the screws that fix it to the respective supports, so that it can be removed from the center of the frame: once the engine block has been released, you can loosen the screws that fix the intake and exhaust manifolds.

At this point, you can loosen the screws that fix the cylinder to its seat: then the piston inside it can be freed from the connecting rod in order to access the internal components and eventually replace them with new spare parts.
