Check locally (I'm in Canada) for oil analysis service. For a modest amount, specialised laboratories analyses a sample of you engine oil and can tell you a lot about the motor condition.

Same situation here...some flakes in the drain pan of my 07 GSA today after changing oil (40,000 miles on bike, was 3200 miles on oil). Mine looked more like aluminium than brass. Bike runs great other than a clatter from the right side head at startup. Changed the cam tensioner spring on that side a while back with no real improvement.

Anyway...I will be sending in an oil analysis so curious what the results are. For only $30 seemed worth doing.

Thats exact same miles as mine and on my first oil change i had a aluminium pulp/fine ground texture plus brass looking flakes, so far iv removed big end bearings and no wear there and crank looks good

Yes, Ill be sure to share. Went in the mail for tommorrow so should know in a few weeks.

I was thinking of starting a thread with oil sample analysis results, have not looked to see if there is one already.

Not quite ready to tear my bike down like you have...hope it comes back ok!

Iv taken lots of photoes of the tear down so ill put together a working instruction. It would be nice to see a full engine in bits so i can identify the brass component, who know it could be a gold ring that slipped of the last guys finger ? Lol

Started an Oil Test Report/Results thread here. Glad my engine got a clean bill of health!

It came back good:
This sample from your BMW
has a lot to like. Universal averages show typical wear for these 1170cc engines after a 5,200-mile run.
Your metals are low after a shorter run, and the balance is what we'd expect from the engine type as well. If you keep oil change intervals consistent, we'll just be looking for similar wear levels going forward. (Stable wear trends do even more than average wear levels to show the engine is healthy.) The viscosity read in the 10W/40 range, right where it should be.

I posted it here:

So a update to my rebuild and metal particles in engine oil, iv covered 900miles no running issues, every 100 or so miles iv dropped oil and filtered it through a coffee filter, every time iv got less particles in the filter, so im thinking do i just run it,? Or maby take front timing cover off and inspect around the timing gears ect, any thoughts appreciated
