FX4 BTW: valve ticking on these motors is healthy, be concerned when you have no ticking.

FX4 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.

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.

volusiacrazy I just add a cup of saw dust once in a while to quiet them.

mdhyre Some say the Lucas stabilizer is going to wear out on me and noises will return. Its been six weeks and probaby 500 miles plus or minus. The bike still runs smoother than the day I got it (7,500 mi). Jury is still out on this but I'm still enjoying the quieter engine and I'm still pro Lucas Oil Additives.

No what im saying is some people swear the gaps get bigger whereas others say they get narrower, which means people just arent measuring correctly as two identical factory built engines cant have one going looser and one going tighter, so its human error.

Ive not touched mine and the bike is on 14000, as long as I can hear them and they're not too loud im happy.
