As John said it should be done as a base line and it is rare for them to need adjusting at 12K.
I called out for a Tech Session and through a great group of people and I got to check mine at 14,000. I am now approaching 25,000 and need to weather 3 more months of winter riding and will do it again.
The reason being I had some exhaust valves that were toward the tight side. Still in spec. but on the tight side.
This forum schooled me that with the LT Motor the valves wear tight. So you don't get valve rattle, but rather burnt seats and valves and after that the sky is the limit. Worst case of neglect of course.
So now I have a reference. I would have been freaked at 24K to see them on the tight side with no reference to go by. By all accounts these bikes hold valve clearance very well. My Dealer (when I could still call him that) flat out told me they never adjusted a 12K LT, 24K very rare and most in the 36K and beyond.
So I will be able to proof that out on this check. If they all check to the 14K, then indeed mine was just put together on the tight side.
However if they have tightened still tighter I will need to do some " bucket figuring" and go through the process of changing them out toward the loose side again.
I will be a bit anxious if they are tight but with help from here I will get through it.
Long and short of it if you have it apart that far, it is not a big deal to do. The gasket can be reused with the appropriate amount of RTV sealant in the correct areas that are apparent, and a helper to turn the rear wheel to turn the valves into position to measure.
You seem fine on turning a wrench so you should have no issues with a search on the topic and getting the sheet someone made up to mark your valves as you go. Uhh there are a few of them in there and this person deserves big props for creating it to keep track of them. You tend to jump around a lot to measure the next available valve in position, unless your help likes turning the wheel
