Motorcycle doesn’t start

Moin This winter my motorcycle (Honda VFR 750 f 1988) didn’t sleep well when I tried to start it turned the starter engine at all, so I checked the battery, loaded it, but the engine still didn’t start. When I turn on the ignition, only the oil lights and the neutral light don’t shine, although I’m in neutral. So I thought that the start didn’t work, because the electronics don’t realize that I’m in neutral. I also found out that if I’m in a gear and keep the clutch in place, I’m still not in idle, but the gear is gripping, but that’s another topic. First I need your help to get my bike started again. LG PS: YES the engine on/off switch has been flipped.
