OK some dumb newbie questions, what specifically needs to be done to winterize a bike? Like the guy a couple links down, it’s been 25 years since my last bike and I can’t remember. Other than taking the battery out and keeping it charged what specifically needs to be done to the bike? Oil change, drain the fuel tank, official HD servicing? Any of those? Anything else? Is it not good to park it in the corner and leave it on the kick stand all winter? Does it have to be on a rack perfectly straight up and down? OK to leave tires on the ground?
