That's right. Recommended valve clearance check intervals are based on mileage only, not elapsed time... I had an exhaust valve clearance just under spec at 0.20mm when I checked at 2600 miles. I just thinned and switched some shims around, to set all my inlet valves' clearances at 0.18mm, and exhausts at 0.26mm near middle of spec range. I used wet fine emery cloth on a flat wooden table to thin shims.
You can get 7.48 mm diameter shims (as on Versys) in 0.025 mm increments (instead of only 0.050 mm increments) in 2.50 mm to 3.50 mm thicknesses.
Suzuki 2004-2005 RM-Z250 shims $8.47
Kawasaki 2006-2011 KX-250F shims $8.96
(Versys shims 0.050 mm increments $11.78)
