Who has adjusted valves on their WR 450?

...Or any of the WR/YZ's for that matter. I checked clearance at break in. I am now at 500 miles and figure I should check again (even though the manual says 500km). I am curious if any one has actually had to adjust their valves at this point? Should I stop by the Yamaha shop and get a selection of shims before starting the job?

Thanks in advance for any input,


Yeah I had to do mine at 2000 miles a few weeks ago. I like to keep them on the tight side. They were on the upper end of the tolerance. :)
