06 WR450 Valve shim limits

2 posts in this topic

 On the older tappet valve motors I always set the intakes at the loose limit due to the valves sinking into the head over time, I also set the exhaust valves at the tight limit, they get looser from carbon buildup on the under-side of the valve.

 

Do the shim motors act the same way over time?

 

Has anyone had the exhaust valves on the wr get tight over time?
