Since the adjusting bolt had a pitch of 1mm. If you turn it 360 degrees, it will advance 1mm. To adjust IN:0.25mm and EX:0.30mm, tighten the bolt and valve until they touch softly, and then turn it back XX degrees. But even so, I’ll check it with a thickness gauge.

I forgot to take a picture, but the crank can be accessed by removing the inner cover of the right tire, and the bolt size is 19mm.
