My wife and I had a 2008 Hyundai Santa Fe 3.3 liter V6.
Recommended valve check at 60,000 miles.
With a house in Las Vegas Valley and shop in Ventura County, CA, I commuted alternate weeks for about 10 years.
At that time, the service manager at Victorville Hyundai (mid route) was someone I trusted.
Around the 60K mile mark, I took it in to be checked.
Listening to the engine idle, with hood up, he advised me to not open it up.
He further advised that none of the ones checked needed adjustment.
We drove that vehicle for over 140,000 miles, until 2016, without ever touching the valves (bucket shim type).
The only issues were a TPS (limp mode) and later a CEL for the two fuel tank sensors not being in sync (replaced fuel pump and fuel sensors). It ran strong at the time it was traded.
Back to the CB1100:
Too much gap should be audible, certainly with a stethoscope, if not drowned out by the injectors.
The issue would be not enough gap, resulting in a valve not fully closing and burning that valve.
This would not happen from cam or bucket wear (open gap), but from a valve settling into its valve seat...which would likely happen during its early life.
Based upon reports on this forum, that is not happening.
At this point, the valve clearance check intervals seem extremely conservative.
