Thanks for your very quick answers guys!
- 750hp, I'll try to make pictures of the bike and upload them ASAP.
- Black Superduke, thanks for this very interesting remark. I don’t think it comes from this switch though because the headlight cover is still original and the problem doesn't happen when I turn (sideward movement) but when I brake hard. Also, it only happens when the tank is less than half full (it doesn't happen if I make stoppies with a full tank).
I really don't know how to solve this problem at the moment, apart always riding with a full tank
