I did some snooping around there and it seems the folks who took the bikes to dealers had mechanics who "said" the valves were in spec, which working in several MC shops over the years means they were too lazy to check.
Apparently it is a big job of up to 7 hours of shop time to do the full procedure.
Sounds like a good long running bike though.
