Plastic in oil strainer?

I just changed the oil in my 2015 yz250fx. Have owned it since new and it has 80 hours on it. I have probably only checked the strainer a few times and probably not within the last 40-50 hours. Anyway, I decided to check it tonight and found a bunch of stringy white or clear plastic pieces on it. Any idea where these could have come from? My only guesses would be from stator or Teflon pads in my rekluse. I can't think of any other whitish plastic in the engine.

That was just for size comparison :) it was the penny I used to hold the gears when I replaced the clutch basket.

Timing chain guide possibly

That's where I'm leaning now. I forgot one of the guides wasn't black. I'm going to continue to rub it and keep an eye on it. I'll do new guides next time I do the top end.
