Hello After more than a year I would like to bring my Aerox back to the front. I would like to make a checklist and if it goes right away. Hope you can add my list and possibly post left for the parts that I lack. 1. Charge the battery?!? Did you connect to my charger but it does not matter. Turn it a 5sec push on MODE until it then from 12V switch and that’s it, normally he should recognize the Ah. Think the is over because k Since the thing is 5Ah but should go or?

Detach spark plug and check whether it is deer brown, but since the scooter 1.5 years was better than new. Thought on the here, your opinion?
