Greetings from Finland and help needed!

[Tilves]

Hallo!

First, I´m sorry I write only in English, but bare with me

I´ve been a proud Freewind owner for a year now and not have had any problems with my bike, until now.

Last week I did a normal oil change and two mysterious metal pieces came out with oil from engine and I can´t figure out where they are from?
You can find a picture here:

Everything is running ok and there are no strange noises when engine is running (yet!?) and there wasn´t any other sights of metal in oil or in oilfilter...

Can anybody here make a good guess, where those are missing from?

Regards
Matti

Just an educated guess: Pieces of a broken bearing cage, but I'm too little of an expert to say for sure.

I would not use the bike anymore unless a mechanic has told me otherwise.

This both look like pieces of bearing retainer, or even possible a bushing.
But in that case your engine wouldn't do any round more.
Show the metal pieces to a mechanic and let him check your bike.
Please let us know what kind of component we saw, when you figured out.
