Under valve cover 2015 R18 doing #4 service

[Revving2Redline]

Almost all were still within spec. 2 of them were ever so slightly lose. I had our master tech at Honda over see the procedure. Coolant also was replaced and I have pics to post of the used spark plugs. Valves weren't even noisy but the 4 came on dash so I decided to take care of it. This is Bitog so getting OCD about car care is pretty normal.

Once again, this valve adjustment turned out to be just the check (well almost). Most well maintained Honda engine will not need actual adjustment at 100K.

One can pay $400 to the dealer and would have no way of verifying that even valve cover was taken off during this service.
