Can anybody help identify this?

i just removed my front sprocket cover and this small black rubber cap fell out. I have no clue where it came from. It looks like a valve stem cover from a tire without the inside threads and is made of rubber.

Looks like a cap for pair valve, or open airbox plug, or normal airbox plug after pair removal. Just guessing.

I agree, looks like a vacuum cap or plug for an airbox mod.

Thanks for the ideas. I just purchased new air filters so I will check the air box when I replace them. Has anyone seen this cap on the air box before? I know my bike doesn't have the pair mod so maybe goes on there somewhere.
