Model: Gasgas Ec 250
Part: Valve

To replace the exhaust valve on the GasGas EC 250, completely disassemble the motorcycle engine, removing it from its housing along with the exhaust pipe. The exhaust valve attached to the engine can then be disconnected by loosening all the bolts that secure it to its housing: at this point, you can completely detach the valve to insert the new replacement part. The valve should now be positioned and secured back to the engine block, then reassemble everything onto the motorcycle frame.
