I´m ver happ with my ´85 Cali II, better than I remember my old one from 12 or so years ago. One thing though, is it possible to get rid of the air drumming around the helmet when the windscreen is fitted? I´ve tried it set at as low as it´ll go on the mounts and about half way; this just moves the area of turbulence from exacly where my helmet is to a couple of inches behind. It still shakes my head around in either position. I´m 5´10\
