Oh people do it - and every time I see it I make a point to tuck next to them, then sit up and wave my arms around in the air like I'm going to go flying off the bike.
Painted wind screens are queer, though.
Buy a mini and race it at a go-kart track...
CPR races all kinds of minis from YSR/NSRs to mini motards (like my KX), etc. etc.
Google the Ohio YSR leauge, lots of good guys...
