Quick valve adj query.

This query is to all of you that set your own valve lash....

I went to do my 3000 mile check and found that the right intake valve had eaten up all
of it's play since the last I set it... I mean no clearance at all.
All the other valves were about dead on from last check.

First) Do your clearances wear open or closed?
Second) Have you had a valve all of a sudden sink in it's seat or the like?

Valves tighten as they wear & don't usually move that quickly unless you were off on your last adjustment.

So now I'm confuzzled.
My first adjustment wasn't long after getting the bike. I did it cuz I was starting to get a lot of valvetrain
noise from the head area. I set very precisely and noise was gone.
They were all way to much clearance.
This time I felt the need to check again because of noise from head....
I find 3 valves dead on and one valve down to no clearance.
Reset the clearance and now the extra noise is gone again.

Have no idea what to think now.

A little uncommon as valve clearances normally tighten.At the valve sinks into the valve seat with wear the clearance between stem & adjuster decrease causing the valves to get tighter.But your case is not unheard of........Just ride & keep a eye on her.

Could it possibly be that you didn't nip up the locknut sufficiently, when you set the valves, and it's unscrewed itself?

Nope. Plenty tight.
I'll just need to keep an eye on this.
