I have a Yamaha Cygnus 125 bought in 2010. I need to recharge / change the battery, but I am unable to remove the cover panel.
The battery is situated in the back, under the seat. The panel got two screws, but they seem to turn without moving. I have also tried to force the panel open with a lever, but it seems to be blocked.
The manual just say "open the panel".
Is there an unusual / unintuitive way to open that panel?
