Good morning, in all seriousness, I have two views to consider. First, as you mention about originality, if you plan to show the bike in the future where such things add point towards a trophy, you must keep them on. The bike must remain stock and pure. If you also bought the bike to hopefully make money on it in the future (or at least keep high resale value), then again, keep the stickers.
For the other thought, if the above are not within your scope, remove the stickers carefully and ride the living heck out of the bike. After all, one does not stop having sex with their wife so that she is fresh for the next guy.
