This came out with the oil......
It's one inch long and I estimate one mm wide. (seal ring?)
Any idea from where?

Starter sprag?
I am not sure on the terminology here, but it maybe the spring that is around the oneway bearing at the starter gear.

that's the sprag
and yes, it definitely looks like it
That definitely sucks. And another vote for sprag.
Thousand dollar question:
Side cover?
Cases?

Side cover [thumbsup]

left side cover
remove the flywheel
if you're lucky, it hasn't completely exploded. you might even get away with just putting on another spring. i think those bearings run about $200 now.

Thanks guys [thumbsup]
Is the bearing and seal one piece - this spring securing a tight seal? (or, in my case, not?)
Where does the oil travel from and to if there is no sealing?
Do you think the seal will perform without the spring?
(I'm asking because I want to explore the possibilities of riding until this engine's next scheduled cover removal - four weeks)
If that spring is only one inch long and only one mm diameter, I don't think it could possibly be from the sprag.
I'd say it's from a very small seal.

sprag spring broke
when my sprag blew i had this same stuff in my oil, except mine was in 4-5 pieces..
that being said, if the bike still starts, it's probably not the sprag

I don't know if this is the complete length, but it IS about one mm thick
Suggestions?

Bike starts normally. Wouldn't it from the seal broken, but with a functional bearing?

the spring on a sprag is not a seal. it's a retainer. it circles the race and holds the bearing together.
Given the bike starts normally, I'm gonna say it's probably NOT the sprag. If the retainer spring on the sprag breaks, it is usually a KAPLOOEY for the bearing.
I should have asked about that before..duh..
Gotta agree with ducatiz. If that is a section of starter sprag spring the starter would turn, but the engine wouldn't
sorry to mislead you but the spring look so big at your picture.
If it is only 1 inch in its stretched state in your picture it most be coming from a really Small seal.
The clutch side on the clutch push rod have one Small seal on the dry clutch models.

twas brillig!
I was looking at the schematics for where that thing could've come from - geez good luck. There's a bunch of little bearing units. It actually reminded me of the seals on the Showas, but it's way too small. And how the heck would one of those get into there.
I'd try looking at the shift shaft seal first to see if it's loose or working itself out. That could be done without taking anything apart. Then there's a bigger seal similar to it in the clutch cover where the crankshaft end is supported.
Then there's probably three types in the crankcase at various spots but that may require splitting the cases.
It was from a seal around/by a valve.

Glad you got to the bottom of it Lars [thumbsup]

... and I'm glad it didn't end up in a more critical place - potentially messing up the head :P
