Take a quick look at this topic below, as i did post some clearance values:

GV 125 S Valve clearance

Also , report back to this thread when you spin your engine 10x , then recheck clearance, it might change 0.05mm to 0.07mm , although let the bike cool down overnight and do it on a cold morning as heat does affect the clearances.

If the markings inside the engine look like pen-markers like the green one, that’s what Hyosung did during production, as long as nothing looks broken.
