While at work today, I got to thinking about how dirty my air filters are. I managed to convince myself this was causing my problem. So when I got home I pulled them off to clean them, and while they were off I went for a short ride. This didn’t solve anything. But on the plus side I was able to deduce a few things. 1. The problem is there cold as well as hot, so valve trickery seems less likely. 2. Because it was warmed up I tried george's trick -

CRIFNOTE VERSION: Check pipes to see which cylinders are firing
That's an awesome trick. This is my first multi-cylinder bike, I wouldn’t have thought of that.
And with that method, it was pretty clear I've dropped both of the inside cylinders. These bikes have two coils, right? By chance one coil doesn’t fire the two inside cylinders, does it? Can the coils be accessed without removing the gas tank, to check for loose connections?
The bike is cooling down now, then I'll go pull the two spark plugs out and see if they throw any light on the situation.
I’ve managed to wrangle some time off of work, next week. I was planning on taking my new bike a on a little tour around northern CA/NV to show it off to friends/family I have up there. I could take the KLR if this isn’t solved, but they’ve already seen it.
