Me too. Since I completed Givi Airflow with side wind flaps (DL1000 '14), my speed is completely out of control.
I remember, 2 years ago after I've finished my setup, bike started to go a bit out of control in some corners on the road I use every day to go to work. First I couldn't find out what was wrong with the bike. Took me few days to understand that my speed increased a lot in those corners.
Even now, two years later I sometimes think: "Why the hell everyone is driving so slow today...?"
