To replace the piston on a GasGas 300, you need to loosen the screws that secure the front part of the exhaust so that it can be completely removed, giving access to the components inside; once the part has been removed, disconnect the connectors attached to the engine, then loosen the screws that secure the cylinder at its top. This way, you will have access to the piston, which will be detached from its conrod by removing the retaining ring; after the replacement, you can reassemble all the components that were removed earlier.
