Hi guys. I just went to do an oil change on my 2017rmz250 and found the strangest thing that I've ever seen. I removed the oil strainer next to the gear change lever and was totally dismayed to see that the oil strainer was completely clogged up from the outside with something. On closer inspection it seems to be chewed up pieces of clear plastic film, something like what you would see from a plastic bag. I am at a complete loss as to what it could be or how it could have gotten into the engine. I can post some pictures later, but I'm just getting ready to remove the flywheel side and clutch side covers to see what else might be in there.
The strainer was pretty blocked, so I'm hoping it hasn't done any damage to the top or bottom end through oil starvation. Has anyone ever seen anything like this before? Thanks in advance.

Sorry for the poor quality pictures, but hopefully you get the idea. The only thing that I can think of was maybe the oil bottle from the last oil change was contaminated and it got into the engine when I filled it up. Other than that I can't for the life of me think where it could have come from.
The main oil filter seems to be clean so it doesn't look like it's made it's way out of the gearbox. Do I need to tear the motor apart? Opinions please, thanks in advance again.
The bike isn't new, which makes me think its a seal tearing apart.
The Shop
Either that or someone smuggled crystal meth across the border in your engine.
Edit: after seeing the pic below I doubt my guess is right. lol
I've just checked both oil containers that I've been using. Both have pull out spouts with no plastic film that you need to remove before filling. I've used the same oil from new (same bottles) Putoline. I've always boyght 1 litre bottles and the last time I purchased I got a 4 litre container. Deffinately no film lid that you need to remove before unscrewing the cap.
The only logical explanation is the oil must have been contaminated. I can't think of anything else. It's deffo not part of an internal engine component that's shredded itself. The latest pictures just show the largest piece.
My neighbour is definitely not happy with me, but she wouldn't have a clue how to get some plastic in the engine. It's not what you might think either. We've been, as we say here in England friends with benefits, although the benefits have recently grounded to a massive halt!!!
Pit Row
I will definitely lose sleep over this.
Plus, that's a lot of plastic. If you were filling the engine, you'd see that. Did the clutch you put in have parts wrapped in plastic and not take off? Like new plates or something?
Maybe something fell into the container when it was being filled at the Putoline factory. There seems to be some red colouring on a couple of the bits. Print maybe, but there's no way to make out what it is.
Also, the Rekluse core exp 3.0 uses the original clutch friction plates.. It did come wrapped in bubble wrap, but I was playing about with it and looking at before I installed it, so I'm sure I would've seen anything on it.
On closer inspection it does look very similar to the bubble wrapped bag that the Rekluse came in, although it feels slightly more rubbery, but the oil may have done that to it. There is a definite straight edge on the piece that I just photographed, like a cut and possibly an outer skin that may have been one of the bubbles. Maybe a piece could have been tucked away in the machined holes in the pressure plate or the clutch hub, although it's hard to imagine that I wouldn't have seen it at the time.
Maybe we have an answer, but I suppose I'll never know for sure.
I'd use some cheap Dino oil like Rotella 15w40 or whatever you have there and dump it each ride and clean filter a few more times.
Once it stops then run your regular favorite.
