I have a 2019 N1K and haven’t done much to it. It’s still a baby. Bought as a left over about 6 months ago brand new and still under 1k miles. Was thinking to do an Ivan flash of the ecu and a full 4-2-1 akropovich exhaust system on the bike. Would there be any other tuning or mods needed to do? Really like what the Ivan flash provides and love the sound and drop in weight with akro.
