My 2013 was checked at 26,000 miles and all in specification , plan to have my 2018 checked at 25,000 and if they are in specification I will probably never check them again.
Goldwing was checked at 50,000 miles and needed some shim changes, had them checked twice since then and they were still in specification so it was mostly just wasted money. The Goldwing turned 560,000 miles yesterday and still runs like new.
Mine were all in spec at 26K but when I checked them the next time at 58K (I know I was late) all four exhausts and 3 intakes were tight.

I believe long haul paul was given those bikes for free form Yamaha. If I was given a bike I might skip some maintenance on them also .

Just had my 2014 checked and adjusted at 50k (miles). 6 of 8 valves were well out of spec and 2 were on the edge. I bought the bike with 45k from the original owner. He said they were in spec at the first interval. Dealer quoted me “about $900” to check and adjust. I found a highly regarded local mechanic who quoted $350 to check plus $100 if adjustments needed plus $50 for plugs and coolant which he usually does at the same time. I was out the door for $489. Never in hurry to spend the money but happy to have this out of the way.

We just did two Teneres in my garage this past weekend. Paul's bike (2015) was all in spec, but nearing the lower limit, so no adjustments needed yet. Hal's bike (2016) had two surprisingly tight exhausts. Intakes were in spec and the other two exhausts were like Paul's, nearing the tight end but still in spec. Both bikes were around 25K for their first check. I think we've solved the trouble to get the valve cover in and out, but getting the cover gasket sealed is still a bit of a pain. The other issue we ran into was re-setting the tensioner. Luckily I had a spare and it would wind in and allow us to set the clip without any trouble. Hal's tensioner however seemed to have the piston stuck in the second groove with the second clip. we just could not get it to wind in. We swapped in the spare in that case. I used a 12mm socket in a 3/8" drive impact wrench and was finally able to re-set it a couple of days later. There's no real impact imparted to the CCT because there's no solid engagement of the 12mm socket with the piston, but the slight vibration seem to be able to pop the piston past that bottom groove/clip and let it wind back in. We'll hang on to that extra tensioner for the next tech day. My bike will be due for it's third check in another 3-4,000 miles.
