Wr450 valve adj.

I just checked my valve clearances at 150 miles or so.They are within tolerances but I was wondering if any of you guys have had to actually adjust yours, and at what mileage?

I did mine after 3000 non racing miles (trail riding). They were on the loose side just above spec. You want them on the tight side but within spec when you redo yours. :)

I had mine checked after 650 miles and they were within spec and no adjustment was required. :)

I was just out of spec on both exhaust valves at 355 miles. Intakes were in the middle of the range. I mainly rode trails and sand pits.
