Shavings and powdery to a fine granular particals are two totally different things
Shavings will block and slow down the flow of oils through out their patterns. Where the finer stuff will either get pulled by the drain plug, or carried by flow.
my advice to anyone buying an M8 is to not leave the dealership with out a K&N oil filter installed
Those are made with a hefty magnet that grabs and holds all metal particals before they get recycled back into the motor

Hello..just bought a 2017 SGS about 2 weeks ago..so I have some Skin in this Game..I am trying to understand how the Oil Filter is not picking up the metal Shavings in the oil..I keep hearing about a check valve in the Oil Pump Assembly ?
I had them throw in the service manual so I will look through the oil flow diagram and see if that sheds some light.
I have 411 miles on her as of today..have been keeping tabs on threads like these to see what's what with these M8'S.

Not to start a debate but your engine oil does not pass thru the oil filter on every pass. The bypass valve allows oil to BYPASS the filter when the filter pressure reaches a certain point either due to a dirty filter, or pressure, thus you still get lubrication to all the important stuff. I am not saying your oil is not filtered, just that if you took one drop of oil and watched it flow through your motor, it may or may not go through the filter each pass or lap. Hope that makes sense. This is exactly why some people swear by the surgical stainless steel filter media available in some aftermarket filters. They flow close to 100% of your oil each pass.

Well you will cuz it's wrong.. All the oil is filtered unless the filter becomes plugged.. Reading too much Donney eh?

I do swear by re usable oil filters. Forget the brand I have on mine, but love not having to throw used filters away and I think they're better than traditional oil filters
they pay for them selfs after the third use

Add me to the list of oil light comes on at idle.
I have excessive blowby from the aircleaner and now the oil pressure light comes on at idle.
I took a video of it. I went out for a little ride at highway speed. Rode about 5 minutes. Pull into the driveway and shut it down. Grabbed the camera and started it back up.
Oil light on, rev it up and it goes out. Comes back on again a few minutes later. Oil level is about 3/4 of the way to the top of the full line.

400 awesome miles on my ultra limited so far. Went through 2 tanks of premium gas. That's only 33.34 mpg. Seems low to me, compared to what I'm reading on these forums. I'm assuming it will go up as it breaks in? Some highway, some city, and some back country roads. I absolutely love this bike. Hopefully there no issues.

My two cents...
1. Don't worry about oil pressure/shaving issues! Ride the bike and enjoy it as so many other are.
2. If you can't help yourself but to worry, add a cam. The whole cam chest is disassembled along with the oil pump. If there is any scaring, you'd see it or the tech would see it. Then ride and enjoy your bike.
