I still have an old photo from where I looked out my apartment (3rd floor) one fine morning to see my bike in full side profile.
Grr...it leaked most of the acid out of the battery, onto my seat pan and seat cover, ruining the cover overnight. Broke the brake lever, took the paint off the back of the oil tank, too. Scratched up the fairing, bent the engine crash bar, too. Whoever did it drove off, because the car next to my bike had no scratches on it where it would have had them from hitting it.
Check your battery level?
