So I was running on I-71 and passing a Semi on its right prolly about 80ish +/-, and the C-14 began to wallow,low frequency, but feeling like the beginning of a tankslapper--been there paid for it. I rode for about an hour before, I think, I figured it out--my OEM top case on because of ride w/ wife sunday. I thought well ,not much experience with it, though I think it caused an airflow issue with one lightweight guy and the airflow back on to the case.
I have the OEM Givi Mono and am wonder if anyone has experienced this ? I chuckled when I read the 80 MPH caution, but really?
