Why I am selling my Dart Flyscreen

I bought the classic flyscreen by Dart in hopes of reducing wind noise on longer trips. Sadly, it did the opposite and created buffeting that increased the level of noise to an unbearable level. I am 5'11'' with a 32'' inseam and ride a 2018 Triumph Bonneville T120. Based on my testing, I would need to be at least 6'3"' tall for the flyscreen not to negatively affect me.
