If it were my bike, I would do an adjustment myself. Use a torque marker on the nuts to see if they move. If it doesn't hold and the nuts have moved, I would readjust and install new lock nuts. If it still doesn't hold and the lock nuts are staying tight, then I would look into replacing the cylinder head. Last time I looked they were going for US $150 shipped on AliExpress, probably cheaper to your location.

Well my total mileage for this bike is around 35,000kms.
I'll have to check with the mechanic on how he made the adjustment last time. and ask him why it kept on changing for only a show period of time.
might as well source a new head for this hehe
