Model: Gasgas Ec 300
Part: Valve

To adjust the valves on a GasGas EC 300, loosen all the bolts securing the cover on the right side of the bike, which contains the valve mechanism. Once the cover is removed, access the underlying valves that need to be adjusted according to the specifications in the user and maintenance manual, using the appropriate tools. You can also check the valve clearance using a feeler gauge: after adjustment, close the cover by securing it with the bolts.
