How many metallic particles are normal in an engine with a wet clutch?



My bike, and the bikes of everybody I checked have numerous tiny metallic particles in the oil, only observable with a flashlight or sunlight.





I'm guessing this is normal for wet-clutch applications?

Depends on what color they are. From what I recall if they're aluminum it's normal, if they're copper-colored it isn't so good.

More like if they are aluminum then there's still hope. If they are copper colored kiss your engine good bye.



This is where the aluminum comes from.

Already did that

I should mention that this is the second oil change since the cam chain.



Edit- Also, before I did the chain there were pretty noticeable aluminum scraps in the filter. There are none now. The particles that i'm talking about now are all but microscopic.

Some metal particles may be present especially after the cam-chain swap.This is why I recommend changing the engine oil and filter after any major work after say 50/100 miles.This will help prevent any that may have been missed by the filter and oil pump strainer.



Oil changes are cheap and easy,engine re-builds are not

I'd do it again @ 500 miles just to be safe.Then you can go back to routine.



Don;t forget to change the drive box oil if you haven't already.It often gets overlooked and is just as important as the engine oil.

There's always going to be some microscopic particles, even on new engines and anywhere inetween.

Drive box? For those of us who don't speak the Queens English, I believe he's referring to the Final Drive.

I had some fun with Nippongreen and his West Midlands dialect at the Amish too.

Changed the oil and 99 % of the particles were gone, and the ones that were left were smaller. Went for some long ride with no increase in particle concentration...





Looks like it is just left over stuff from the cam chain.



I guess for everybody else: After the cam chain job, it can take several oil changes to get all of the smallest particles out, even if you cleaned the inside of the motor well when you were in there.

Good news.Yes it can take a while to clear the oil from dislodged debris when doing major engine work hence a couple of quick oil changes will pay dividends in the long run<sic>
