Scooterotica

I've been wondering about this for some time. I have a tool box and lid that was originally from a Greek Jet 200 scooter. The louvres in the tool box door are sealed with a strip of some sort of heavy duty tape. As is the built in kidney air box. I'm not sure if it was a factory modification for the local market or a piece of improvisation on the owners part. Although, I have vague recollections of other Greek Serveta's with a similar set up. The question is why would they do that? Surely they didn't run around with no filters on over there?
