I just changed the oil in all 3 cases this afternoon (no, not starting an oil thread) and in the below picture is the metal shavings from the Primary drain plug. I set it next to a clean drain plug for comparison.

Is this normal? I just don't recall this much on there before. Thought I'd ask. Thanks!

 

Was it with 10000 miles of riding? was it the first or 2nd change??? My first couple of Primary changes looked like that then after about 25000 it cleaned up quite a bit.

Yes for the primary. Its pretty violent in their.

 

primary always has a lot of fuzz due to the clutch plates and metal chips due to the starter gear and clutch ring gear. the chips tend to increase as the bike gets more miles. mainly due to the compression build up as a result of carbon build up. This compression build up on startup causes the engine to bounce back (forcing a reverse tooth engagement cuasing chipping) in as much as you get a bounce back when you pull the cord on your mower. older batteries contribute to the problem since they are unable to maintian high engine spin up making it easier for the engine to bounce back on start attempts. in the later state of this is the infamous start, bang, grind.

 

 

That's great info, educational. Thanks for sharing.
