Model: Gasgas Ec 125
Part: Engine

The operation of dismantling the engine of the GasGas EC 125 is carried out by accessing the central part of the bike immediately under the seat. To remove it from its housing, unscrew the screws and disconnect the appropriate connectors. Once the engine has been extracted, you can separate the two half-cases that comprise it by unscrewing the fixing bolts. This will allow access to the clutch, which can be completely removed by sliding out all the discs; it will also be possible to detach the piston from the corresponding connecting rod after removing the cylinder.
