well supposedly according to what ive read, once uve done all ur winterizing ur technically not supposed to start ur bike anymore. part of the reason is cuz of the cold air, condensation can form in ur pipes when u start her up and can potentially cause it to rust. this however didnt stop me last year from starting my bike once every few weeks. i did not remove my battery and connect it to a trickle down charger.
also make sure to move ur bike a few inches once a week or every other so u dont get flat spots on ur tires.
