KTM 525 exc vs WR450f service intervals on valves

KTM recommends every 15 hours on the 525 exc to adjust the valves.

Yamaha for the WR 450f recommends every 1,000 km or ~620 miles....

Does this sound right?

Pfft I rode 6500 km on my last wr and never checked the valves once

KTM's with the RFS 400/450/520/525 engine should check/adjust valves at intervals no longer than 30 hrs (especially for the soft stock intake valves).
