i bought one from ebay once...they do pop up.. otheriwse see here: PUIG Motoplastics | Motorcycle Exhausts | Performance Parts
I used busters for my last puig screen but swore I wouldnt buy another as it all cracked.they said it was because soap got on the screen when washing the bike so it wasnt covered for a replacement.they said if you get anything other than water on the screen it can crack and isnt covered.
