It could be just that you need to swap -yaxis(1)- and -yaxis(2)-. Note that
-xaxis(1)- is not needed at all.

Sometimes it helps to shift by a constant and then fix the y axis labels.

clear
set obs 20
gen year = _n + 1989
gen y1 = 4 * (rnormal() - 0.5)
gen y2 = 125 + 10 * (rnormal() - 0.5)
gen y3 = y2 - 80
label var y3 "y2"
line y1 y3 year, lcolor(orange blue) yaxis(1 2) ylabel(-10(5)10,
labcolor(orange) axis(1)) ///
ylabel(20 "100" 30 "110" 40 "120" 50 "130" 60 "140", labcolor(blue) axis(2))
