Since Harley is getting so tight with their warranty it seems that if you do anything other than put gas in it you will void the warranty. We all know that there are a lot of things that you can do to make your TG a much better ride but most things will void the warranty. I know that I want to at least change the air cleaner and add a tuner just to start. Later I would most likely change the cam but not much more beyond that. My question is at what point have you felt comfortable enough that your TG was going to hold together that you said screw the warranty and started adding much needed modifications. I'm at 4,565 miles on my 2020 TG and would really like to start making improvements.
