Yes, shim type valve adjustments are required. Yamaha calls them "adjusting pads". They come in a variety of sizes.Old Grinner,
Am I right in thinking that the XMax 300 uses shim-type valve adjustments?
Man, this may also be MY last & final bike choice!
Tks~
See the chart on this Yamaha Parts page and look for piece 13. You'll see they list it numerous times in different thicknesses.

The upside is that the recommended schedule to check and adjust the 4 valves is every 12,000 miles or 19,000 Km.

FWIW I have absolutely no regrets buying my XMax 300. I would do it again . . ..
If I had to complain about anything it would be that I wish the high beam LED was a bit brighter at night. Distant reflective road signs or other reflective surfaces stand out in the darkness OK. It's just that I wish it had a bit more intensity of light on the road surface itself. That said, I don't do much night riding anymore anyways.
I was impressed with how quick it is and I have no problem keeping up with traffic on highways with 65 MPH speed limits. It has power to spare . . ..
