Those titanium valves have that hard coating,on a hard ridden 450 or screaming 250 once the coating goes away the valve needs replacing.
That was 1 adjustment session for an A class cross country CRF450R raced by a young friend,he did all his own wrenching and didnt want to take a chance on a DNF. He would adjust em once,run it till it showed signs of needing another adj and take it apart for R&R.

Pro Circuit has some nice valves,supposed to last longer go faster.
367.00 in actual American dollars for each valve.
Some bikes around at times
