Depends on what part is actually wearing. If the cam lobe or rocker face is wearing the clearance will increase.

The rocker doesn't actually contact the valve, rather the adjuster does, on one end.
On the other, I've never noticed any significant weat on the cam lobes and contact area of the rocker arms.
Usually the valves & seats wear on Japanese motorcycle engines.

Haven't seen it on the Volusia, but I've seen a few offroad singles that have had the hardfacing worn through on the cam follower/rocker arm. Also have seen where the adjuster puts a slight divot in the tip of the valve stem which will give it more clearance in operation than what it measures with a feeler gauge.

Psych0 knows what he is talking about.
My note: I would be concerned about using an oil thickener like Lukas causing premature engine wear during cold starts. Yeah, it may help for a while with warm engine noise but I believe you will find it causes premature engine wear over time.

BTW: valve ticking on these motors is healthy, be concerned when you have no ticking.
