it's stored in an unheated garage, and i have no block heater for it. for the winter, center stand, charger, disconnect negative lead: yes; leave a few liters of fuel and dump this in spring time and replace with fresh fuel. the bike is grumpy when cold even during summer, so i'm going to look into the wiring for the temperature sensor, because the jetronic doesn't seem to know when the engine is cold. with a diesel i would add fuel stabilizer, but not for petrol.
