.006 and .004 is it a set of valves for the Z40 racing cam? Thank you.

FullChrist yes. If I were doing a race I’d probably have them lower. Around .003 and .002.

Excuse my english I'm from Québec.Where you from?
In your video you install your racing cam.
I would like to calibrate my new racing Cam.
On a YX140 engine the setting for the valves with an original Cam is 0.15mm (.006) for the air inlet and 0.10mm (.004) for the output exhaust. With the racing Cam Z40 how much should I adjust the valves?
How you calibrated yours?
Thank you... I wish you a good day.

I think I reversed ... in and out.
