2 Stroke 2020 CRF250R

Buddy of mine picked up one of these, and he asked me to advise on maint, so I was reading up on the specs. Got rid of the buckets on this model, and has the finger follower style rockers.
IN: 0.004 ± 0.001 in (0.09 ± 0.03 mm)
EX: 0.007 ± 0.001 in (0.19 ± 0.03 mm)
How the hell are you supposed to shim this thing? I have a hard enough time finding the right shim size for the tappet style bikes, but these intake clearances are insane.
 
I guess with +- .06mm they are in the ballpark, but tight is a thin feeler and with .05 increment shims Ill have to get lucky. Too damn hot around here to ride anyway.
