Reply To: GV 125 S Valve clearance
I could judge (if i can) if you upload a nice video of the phone near the engine valves so we can hear if the valve chatter sounds OK or not. (try to get away from the exhaust as they are louder than the engine)
Try Motul 7100 oil. Probably the best oil Hyosung bikes can drink and it does help a little bit to calm down the sounds of the moving parts inside the engine (just a little bit!)
Plus your gearbox will love you.
Old ducatis are loud generally and have a dry clutch with adds to the ticking noises but it’s normal for it to sound like a “tractor”.
The GV125-S should have a small bit of valve chatter especially with the rocker arms hitting the tappet buckets , a bit of ticking will occur until its a little warmer and oil is fully circulated before riding off.
