KTM 525 exc vs WR450f service intervals on valves

3 posts in this topic

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?

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).
