Just bought an Electra Glide Classic-runs great.Going to drive it to the winter-rallies. Got any tipps how to start it in below -20°C? Have to use synthetic oils of course.Tipps for how to prevent the carburator from freezing? Do I have to protect the front cylinder from going to cold? Travelling speed is going to be about 70-80 km/h to keep up with the other riders.
