Plastic pin in oil

[AdzventureXR]

Can anyone guess what this plastic piece is from. Changed oil today and this was in my catch pan. Pan was clean before changing as I always check what is coming out of the engine.
One side looks round other is broken off and seems hollow slightly. Strange

Either part of a sensor or maybe from the cam chain guides? Assuming you're 100% sure it's from the engine, i can't say it's nothing to worry about, have you checked for codes or noticed any strangeness?

Did you put the catch tank under the bike before you took the belly pan off?

It looks like one of the push pins that holds the belly pan on, did it fall from the bellypan into your drain container?

I did have catch pan under it before taking belly panoff, so now I'm not 💯 that came from engine but still believe it. Can't see that sitting in the belly pan after a ride. Its roughly same size. Both my dowels are in my part bin.

The plastic is hollow. Not solid. Really strange.

My water pump also started weeping, don't think that would have anything to do with it. I haven't noticed any power loss or sounds. Wouldn't a piece like that end up in the filter or be damaged if it was in the engine?

Took xr out, everything seems OK. No rattle in valves or timing chain. I put it down that it fell into the pan somehow so it doesn't drive me crazy. I'll open it up in the fall and have a look.
