The cylinder walls are within spec and even have original hone marks. Chemicals I used can not wash cylinder walls, even more, they lubricate it additionally. This motorcycle had same condition of the valves many miles ago before I used any chemicals there other than gasoline. Only second compression ring is slightly out of new component spec, the rest is even within new component limit. New second compression ring should have correct gap for new component spec with this cylinder since the cylinder is within spec.
What happened? Why we never re-ring a motor on a stock bore? Did you measure the cylinder bore before re-ring it? Was it within spec?

I'm pretty sure at this point if you told him shooting yourself in the head will kill you, he would say, "Nope. Will only wound me and my cognitive functions would remain within spec." After which he would post a picture of his cat's brains blown out attributing it to "weak synapses" and him posting enormous pictures of a high performance solution he milled up on his CNC machine.
I have installed the new rings. All rings end gaps are within limit. Here are my measurements
New rings
Cylinders and pistons have been preassembled and are ready to go on the engine
If you run into any more issues the blame can clearly be placed on the former Buell Motorcycle Company. No wonder they went out of business, losers can't even build an engine.
My main concern is the engine is leaking. They need to improve their engine sealing, probably increase sealing faces area, redesign gaskets to have at least double sealing lines on each place, maybe use double o-rings sealing where they use single o-ring. They also need to increase PCV valves holes and hoses diameter to reduce breather resistance and pressure inside the engine housing. It will make the engine slightly heavier, but I prefer to ride heavy but reliable and maintenance free engine.

If you are looking for perfectly reliable and maintenance free, you bought the wrong bike. Like the opposite end of the spectrum. You will never make a Buell meet those requirements, and thus you will always be disappointed. You should look at a Honda Goldwing if you want heavy, reliable, and maintenance free. I've had one. It was exactly that. You will be happier.
I'm sure is is possible to make Buell more reliable, they just need to collect all users feedback and users experience reports and put more engineering effort in this thing using best industry practices.
