Any "Noise" that should not be there, is the mechanical configuration of parts explaining to you they don't like it!
If the complaints are not recognized by the recipients in charge further actions will ensue, and continue .
At some point, the complaints will be turned into paperwork, with large numbers at the bottom of the page,
indicating that you have been negligent.flagerant, indifferent to the complaint dept.
You will have to ante up.

My 2017 makes some valve noise, especially when hot, It actually make more noise than the 3 stock TCs I owned. I don't worry about it. Motor still has fins, If everything is right, the motor will be quiet. If something fits a little loose, it will rattle. Motor likely won't blow up due to the rattle.

Searching out little internal engine noises is futile. If the noise develops into something more, Then you will know what to fix. The saying "ride more, worry less" applies here.

My “little noise” turned into a total teardown and rebuild. New top end, oil pump, jugs & pistons, cam, lifters, etc. I have about 750 miles on it since the rebuild and even though it’s quieter now, it’s still noisier than I think it should be. It’s in right now for it’s post-rebuild fluid change and inspection. They’re gonna look at the rocker assembly, cam chest, and borescope the cylinders. Hopefully all is well...
But if it’s not bad enough to replace the mill, I have ESP, I’ll ride it till it blows. That’s the good thing about a 600W sound system...motor noisy? Crank some AC/DC, no worries.

Not actually hearing the noise, it's really hard for any of us to know where it's coming from. The first engine in my 17 CVO was quiet, but the second engine had a clatter noise right around 2.5K RPMs. I am pretty sure my clatter was a noisy lifter which was reported by several on the forums. Some have had the lifters changed with good results.

This is exactly what you should do. Ask them to ride a different M8, then you both can compare....Also ask them where they think the noise is coming from. Valve train is pretty much the only acceptable place you could get a little extra noise without it causing major damage.

You could also have slightly loose pistons in the bore, Maybe a compensator that rattle a little, A loose part on the exhaust, Some part of the motor / exhaust hitting the frame. A gremlin bell that stuck somewhere between to moving parts. Besides weak lifter, valve stem protrusion might be off a little. Possible carbon build up the the combustion chamber.

Any manufacturer of twin cylinder motorcycles that tells it's buyers that 1 quart of oil usage in 1000 miles of riding is "normal" and within their specifications is confirming that the engines they build are NOT built to exacting specifications and they have a pretty wide tolerance for dimensions in their manufacturing. Their further insistence that .003 run out on crankshafts is also too stringent and should therefore be changed to .012 just confirms what we already know. A am beginning to wonder why we continue to support a company that does not have our best interests at heart. There are way too many owners out there who have transmission migration and/or sumping issues two years after the M8 was first rolled out. Unless I have missed it somewhere the factory still does not have a permanent, proven fix that they are willing to roll out for it's customers for either one. What am I missing here?

I don't think the manufacturer is saying a qt in 1000 miles is "normal." They're saying that if the engine is using that much oil it is still serviceable, but nearing rebuild time. If I picked up a brand new bike and it was using a qt per 1k miles right from day one, then I'd know something was wrong and needed attention, and I'm pretty sure the dealer would agree with me and fix the engine.
If I bought a bike with 30k miles on it and it was using that much oil, I'd figure the bike had been ridden hard, had a fair amount of wear and tear, and was nearing time for some top end rebuild, but for the time being was ok.
Heck some people get upset because their Harley uses ANY oil at all. Some oil gets vaporized in the crankcase breather channel and blown into the airbox and then burned. The hotter the engine, the more this will happen. Some oil loss is normal and expected. And it will vary depending on riding style, weather conditions, age of the oil, as well as the wear and tear condition of the motor.
