Reply To: Valves adjustment – too tight? -GV125S 2022 Clearance Adjust
If you see the metal unthreaded part , it should be stopping the exhaust arm from moving too far away from the spiral thread (and not touching the intake arms). In the older models , we still had to remove the cam shafts. In fact hyosung has made 2 versions of the engine one that uses a screw-top to adjust and yours is classic shim style

I will double check later if there is another way to get to the shims without taking apart the cams away , i envy some newer engines that have a newer screw top , makes life so much easier.
