Reply To: Valves adjustment – too tight? -GV125S 2022 Clearance Adjust
Take a quick look at this topic below, as i did post some clearance values:
https://hyoriders.club/forums/topic/gv-125-s-valve-clearance/embed/#?secret=QXbF27h6tQ#?secret=248HWE90L9 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.
Thanks Marcel,
The engine is completely cold. Clearance is way too tight (0.03 on intake and 0.04 on exhaust) so I need to replace the shims.
I was able to move the rocker arm sideways on rear cylinder but I’m not able to move the rocker arm on the front cylinder (exhaust one is stuck, intake can be moved).
What’s the tip to move the rocker arm? I tried TDC and also every other position of the camshaft but it’s not moving sideways 🙁
