Hello guys, my daughter got her grandma’s laid scooter. Jetz after about 2 weeks of operation I noticed an oil stain in the garage. The oil drips from the Vario. Previously the scooter stood at least 1.5 years ago. I am not quite inexperienced in screwdriver stuff, but n scooter I didn’t have yet. Can you tell me where to start looking, or what the problem could be here? I put on a picture. Thanks in advance Heiko
