Noise when cold Honda XL600R

Im new to this forum and just renovated and XL600R 85 PDO3.
It had drop an valve seat so had the head newly fixed with new valve seats/valves etc (done by a company who usually fix my engines and never had problems with them)
I drilled 0,5mm bigger holes in the farest away cam oil holes- drilled out the bolts etc to make sure better oilflow around the cams, I also changed the rockers arms - gave it a new piston etc....
But now after 50km it started tikking when cold so i decided to adjust the valves again and they where quit loose.....but still the same noise when cold

Is there anything else i have missed or do you have any idea of the problem??

Read something about the cam tension axel- but more or less didnt find it bad when looking

Cold is a relative term, what is the ambient temp?
What oil are you running?

With oversized oil passages, I would expect clicking when hot, not cold.

Just a note of something I learned recently: straight grade oils stick to parts better and provide better start-up protection. Maybe a complete lie, but I am going with it for now on my genset but not my bike.
