I think bikes of that vintage ran anything from 20:1 to 32:1.
A 2001 CR80 runs 20:1 standard. The bike shop keeps telling me it will foul plugs etc.
Plug is clean as a whistle, as is the piston, and piston and rings last.
Don't believe oil makers claims they don't pay for piston seizures and crank replacements.
PM Oldtimer he runs a CR250 not sure what year though, but I would bet he knows.
If you do run different mixture rates remember you will have to adjust fuel amount.
More oil bigger jets, Less oil smaller jets.
You would be surprised.
