have a 2016 Harley Heritage , with only 2,000 miles on it. Air leaking out of the rear tire via the base of the stem valve. I am assuming I need to get the rear stem valve replaced. Going to attempt to do this myself. I've seen others jacking up the bike, and using a vice to break the bead on a tire to gain access to the stem valve. Is there any reason why I wouldn't want to try this ? Curious if there's anything I should be aware of or careful of or a reason not to try this myself. It being the back the tire.
