I was just trying to find out idle tappet settings and so far I found these settings for YBR 125.
Intake: 0.08 - 0.10
Exhaust: 0.10 - 0.12
While exploring these settings, I found a recommended settings from one scientist.
Intake: 0.12
Exhaust: 0.15
Now you can adjust one of the settings mentioned above and share the result that which clearance suited you better. Between, I will also do this adjustment and share my experience.
One thing about valves which I have experienced earlier that more you keep the valve clearance, the more top speed you can achieve while if you keep it tighten then you may get effect on top speed and overall your bike performance like bad fuel average etc.
