I agree with the statement of initial check, however I have owned a 07 and now a 15 650 Versys, I found both with tight exhaust valves on both and my 2015 was at 11,000 KM, less than half the recommended mileage, many on this forum found the same, this statement goes back to 2008, when many were just joining this forum. It sounds like you have the ability to get into this with about the same amount of effort that many on this forum would exert just to change sprockets and a chain. Both Eddie and I recommended this not only to you but for other members reading this. My plan is to check my valve clearance at 30,000 to 35,000KM next time, since the extra effort involved to go maximum was only about 10% more time than if I just buttoned it up, plus I had tight valves. Actually I would need to read my notes, as I recall several intake just in spec , and one tight valve.
A big factor in the valve clearance question is how the bike was set up at the factory. Mass production does not always produce the result that we can achieve in our own man cave. They pretty much slap it together and if within spec then down the assembly line it goes. Being within spec may have some valves towards the loose end of the spec while others may be towards the tight end. In my case I had just one valve right at the tight limit and it was an intake valve, much to my surprise.
I bought a new Yamaha FZ 09 back in 2014. The scheduled valve clearance check is at 26,000 miles. Then guys on the forum were reporting tight exhaust valves at 15k miles, so I checked my. At 19k miles I found all my exhaust valves were tight by quite a bit. Pulled the cams did a shim job and life was good again. All this to say I was quite pleased when I checked my Versys at the recommended mileage and found all valves to be in spec.
Here are the numbers of the FZ09 exhaust valves for perspective: Exhaust: .15/.23 .15/.18 .20/.23 Normal range is: .26-.30mm. As you can see the two at .15 were a fair bit below the tight limit of .26mm. None the less no valves were burnt and compression test showed normal on all cylinders.
I give this example to ease any worries about burnt valves if you have any right on the tight limit. There still is some wiggle room before disaster strikes.
On my bike I am pretty sure the valves are done with their "big" move and have reached their stable, very little movement stage going forward. This is why I am not worried about one valve on the tight limit and will check them again in 5k miles to verify.
