The screen would give me cause for concern.
What year/model is your bike? And how many miles? Some metal shavings are normal from the factory (machining bits when they built the motor...hence the screen to catch them and hold them till the first or second oil change). If your bike is older, then you want to examine the bits closely and get a tech to give you an opinion.Did an oil change the other day and there were a bunch of small metal shavings on the plug and the screen. One of the oil change guides frim this site says that it might be due to crappyshifting.... just changed the clutch as well.... old one was knackered!
Should i be worried?
Don't confused metal bits w/ the grey Threebond case sealant that seems to get trapped by the screen.Here is the 999 screen. the St4 was alot closer to what you are seeing on yours.
My bad. Screen I still say is about normal for first change. The exact same metal flakes on the screen I had on both mine. Very reputable duc shop here told me thats what they normally see. That was 6 years ago. Their explanation of maching debri left on castings I believed as I am a machinst and understand that it could be so.Don't confused metal bits w/ the grey Threebond case sealant that seems to get trapped by the screen.
I'm not so sure that what he has is normal.....could very well be. I agree w/ kaos..... that appears to be excessive amounts of metal trapped by both screen and drain plug. Should at the very least send the pics to his Ducati tech or save the shavings and have them looked at more closely.
spot on....If a magnet picks them up they are steel - gearbox shavings or bearing.
If a magnet doesn't pick them up they are alloy (could be crank plug backing out on a machine up to and including 2000) or rocker chrome chips (a drop of battery acid on them will cause purple fumes)
Ducati don't have an engine number break point on when the change from alloy to steel oil crank gallery plugs was made, they told me the only way to find out is split the cases.
All I know is I have two 2000 engines, one has a steel plug for sure and I don't know about the other one till I strip it.
Metal splinters on the magnet or flakes on the screen are not necessarily a sign of imminent engine failure and certainly not worth tearing down the engine on first signs. As your initial and others have posted, bits like that on the magnet are typically from the transmission's gears. Either because its never been cleaned from new or you're being rough on for whatever reason. I've owned 3 new Ducati's and a couple track bikes, they've all showed signs more or less to your photo either from being new or me thrashing them on the track. Metal flakes on the screen, especially on the older desmo engines are usually from the rockers flaking a well known and documented problem. My suggestion would be to clean everything up good, replace the oil filter and reload with a quality full synthetic and ride it like you stole it until the next oil change interval, <2000 mi. then reassess.
