Correct me if I am wrong but those air filters look like 60s Bonnie air filters.

Not my cup of tea either, I don't like the no rear fender look but there are others out there that like that look, just look at the Speedblaster and Americant thread. I am a tail dragger guy I like a nice long fat fender on the back that almost scrapes the ground. If I knew how to paint well I would have one on mine already.

I learned all I need to know about life by killing smart people and eating their brains.
